1 q= Cs x g x T Q represents heat. Specific heat (Cs) is multiplied to the mass (g) and temperature change that occurred in the reaction. ( T). Specific heat is defined as the amount of energy required to raise the temperature of 1 g of a substance by 1 K, under a constant pressure. Considering the fact that substances have differences, the specific heat varies depending on what substance is being heated.
Heat Capacity... The Heat Capacity itself is extensive (scales with the size of system), but we can think of making this quantity intensive (making it an intrinsic property of the material) by defining related quantities: the Molar Heat Capacity is defined as the Heat Capacity of a homogeneous pure compound (or element) divided by the the number of moles of that compound (or element) the Specific Heat is defined as the Heat Cpacity of a homogeneous sample divided by its mass. The Heat Capacity of any substance is positive. The Heat Capacity is discontinuous at phase transitions. For a gas, the Heat capacity depends on how one does the heating.
Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. As this happens, cooler liquid or gas takes the place of the warmer areas which have risen higher. This cycle results in a continous circulation pattern and heat is transfered to cooler
Pressure is defined as force per unit area. The SI units of pressure are newtons per square meter (N/m2), or pascals (Pa). 3. Slowly drag the temperature (T) slider back and forth. (Note: In this Gizmo, the Kelvin scale is used to measure temperature.
What did Boyle’s experiments convince him about cold? That heat is a form of motion of a particular kind as bodies cool down the particles move less and less 5. How did Boyle explain that substances expand when they warm up? He thought back to his air experiments, and explained that the particles have spring like coils that expand as they heat 6. Describe the earliest alcohol thermometers.

Also, for every force, there is an equal and opposite force acting against it. With the exception of gravity, the electromagnetic force is the force responsible for practically all the encounters in daily life above the nuclear scale. Roughly speaking, all the forces involved in interactions between atoms can be explained by the electromagnetic force acting on the electrically charged atomic nuclei and electrons inside and around the atoms, together with how these particles carry momentum by their movement. This includes the forces we experience in pushing or pulling ordinary material objects, which come from the intermolecular forces between the individual molecules in our bodies and those in the objects. With the exception of gravity, electromagnetic phenomena as described by quantum electrodynamics account for almost all physical phenomena observable to the human senses, including light and other electromagnetic radiation, all of chemistry, most of mechanics (excepting gravitation), and, of course, magnetism and electricity.
The effect of heat on the expansion of gases is stated in Charles' Law. A gas occupies 1/273.15 more space for each 1° C. rise in temperature and, conversely, 1/273.15 less space for each 1° C. drop in temperature. This fact enabled scientists to determine absolute zero (-273.15° C.), the temperature at which all molecules theoretically stop moving. A gas can be made to expand without the addition of outside heat if the pressure confining the gas is reduced. This principle is stated in Boyle's Law.
Static electricity is produced from a process known as triboelectrification. To show how much static electricity an object has, it is determined by its position on the triboelectric series. Its position on this scale is determined by how tight the atom is holding the electrons. An atom is more positive in the triboelectric series if a material is more apt to give up electrons when in contact with another material. If a material is more apt to "capture" electrons when in contact with another material, it is more
