I wanted to see if they would dry faster from air on the hot setting on my hair dryer or the cold setting. My hypothesis is that if I dry my nails from air on the cool setting it will dry faster than the warm setting in 5 minutes. I researched how warm and cool air affects moisture online. I did three trials on hot for 5 minutes and three trials on cool. In my conclusion I found out my hypothesis was correct, my nails were substantially drier in 5 minutes of the cool air
I predict that the lab technician’s Sodium Hydroxide will be a better solution than the one I made myself. So my prediction is that it will take more Sulphuric Acid to neutralise the solution when I use the Sodium Hydroxide that I made myself. Equipment List • Sodium Hydroxide Pellets • Phenolphthalein Indicator Solution • Dilute Sulphuric Acid • Distilled Water • Weighing Boat • Scales • Volumetric Flask • Conical Flask • Funnel • 25ml Pipette • Burette • White Tile • Spatula • Goggles • Gloves Method for Standard Solution Measure out 10 grams of Sodium Hydroxide pellets in a weighing boat using the scales. Place the pellets into the volumetric flask and add distilled water to make the solution 250ml. Swirl the flask to ensure that all the pellets have dissolved.
Instead of having to leave the house to go grocery shopping a person can go online or call and have the food be delivered to the front door. A person can put the dishes into an ever advancing model of dishwashers and have it clean the dishes for them. Now to have our clothes washed we have to worry about what temperature to set the washer at, type of washing liquid or powders, and whether to use fabric softener or not. The use of some technology has made some people lazy and too dependent on the technology to know how to do things for themselves if the need
Explanation: Because of copper is a good conductor compared to water because the electrons jump from one element to the other more easily in copper than water. MATERIAL Copper tacks, a test tube, a test tube holder, a digital balance, a thermos with ~1 dl cold water, a digital thermometer and an electric kettle (with enough water to cover the element). PROCEDURE: 1: Fill the electric kettle with enough water to cover the heating copper. Also fill the thermos with cold water and the test tube to 50% with copper tacks. 2: First you measure the mass of the copper tacks and also try to get the mass of the water in the thermos as close to 0.1 kg since 1 dl of H20 = 0.1kg H20.
The effectiveness of lipase on temperature Abstract Enzymes are biological catalyst that speeds up the rate of reaction. Different enzymes work best at different temperatures, which is also called an optimum temperature. Different enzymes also have different functions. Lipases are enzymes, needed to break down lipids (fats and oils) into the products - glycerol and fatty acids. They work best at room temperature around 36-40 C. Introduction For this experiment, I will be looking at how the change in temperature affects the rate of reaction.
As the students’ lives change, it is especially difficult to find time for personal care. When students are forced to choose between taking the time to cook healthy food and eating healthy or grabbing a quick meal at the dining hall, the usual choice is to grabbing something fast. Lifestyle puts young students at risk for health issues in the future, and short term weight gain. Living on campus, in particular, forces students to eat unhealthy food, which will end up hurting their bodies. Dining hall food has no benefits; unlike home cooking that has better quality, taste, and health benefits.
Rates of Reaction - Marble Chips and HCl In this experiment, marble chips, or Calcium Carbonate (CaCO3), will be dropped into a flask containing Hydrochloric Acid (HCl). The reaction is: CaCO3(s) + 2HCl(l) --> CaCl2 + H2O(l) + CO2(g) The experiment will determine whether or not stirring quickens the reaction rate, which will be illustrated by the slope of the lines in the data graph. If heat and stirring is added to a reaction, then the gas will be released quicker. This is so because when two compounds interact, or collide, a reaction occurs. If the compounds are made to collide faster, by way of stirring, then theoretically the reaction as a whole will start faster and come to completion faster.
● Furthermore, the production line of Barilla had a long setup/change process and was highly automated as well. The manufacturing sequences of pasta production made it very difficult and cost prohibitive to produce particular types of pasta that were out of stock because of unexpectedly high demand. The temperature and humidity in the kiln had to be precisely specified for each size and shape of pasta and had to be tightly controlled to ensure that quality was maintained.This procedure limited the ability to rapidly shift production between different pastas. So it could not afford frequent changes to fulfill sudden demands.So ,if the forecast is unreliable, they would either need to build up huge inventory or lose the customer fill rate, none of them is favorable. Also, the Barilla customers will face stockout due to the low fill rate of Barilla.
On times when the boss wasn’t present, it would make it very difficult to handle the store alone. During that time I had to run back and forth from the deli to the cash counter. The store became a pressure cooker where I had to cook the food as quickly as possible to get all the steam out. During times when I used to get a little bit of free time, I would run to the cooler and refill the
So I ask myself how I can prevent this from happening. Before I give you the answer to my question I will describe a couple of the ways I interact with this behavior. First and for most, the most difficult problem some students always try to overcome, is time management, no not really just that, but rather procrastination, these two behaviors can combine together and cause a huge explosion if not handled correctly. Here are my examples; I don’t do my homework until last minute, I only clean at night, and I don’t like to wake up early to get dressed. I believe I procrastinate with these daily life experiences (Ch.
