TK = 273 + T˚C
T˚C = 273 + TK
TK = 237 + T˚C
0 K = 273 ˚C
0 Kelvin is the lowest possible temperature.
It takes more energy to heat or cool a large sample of a substance than it does for a small sample of the substance.
The particles in 100.0 g of a liquid at 50.0˚C are moving more slowly than the particles of 25.0 g of the liquid at the same temperature.
Boiling occurs when particles are able to escape from within the liquid.
Evaporation occurs when particles on the surface of the liquid escape into the surroundings.
Evaporation occurs at a variety of temperatures.
In order for a liquid to boil, the particles have to have enough energy to escape from the liquid.
When a solid is in the process of melting, the particles are moving faster.
When a solid is in the process of melting, the particles are moving farther apart.
As the temperature of a solid increases, the particles vibrate more energetically.
A 10.00 g sample of iron at 75˚C has more 'heat' than a 50.00 g sample.
Endothermic processes involve the loss of energy from the system.
Calories are a unit of thermal energy.
Heat is sometimes defined as the total amount (the sum) of kinetic energy in a system.
The boiling point of a substance (at a constant atmospheric pressure) is always the same.
On the particle level, energy is transfered by means of elastic collisions.
If two particles collide in an elastic collision, the faster particle will typically slow down and the slower particle will speed up.
The higher the temperature of 25.0 g of a substance, the smaller its density.
Heat rises.
Heat is technically defined as the flow of thermal energy.
The temperature of 10.0 g of boiling water is less than the temperature of 100.0 of boiling water.
Temperature is an extensive property.
Gases have a great deal of freedom of motion.
The higher the temperature of a substance, the greater the volume of the substance tends to be.
The higher the temperature of a substance, the faster the particles are moving.
The higher the temperature of a substance, the heavier the particles are.
Solids have a high Ep.
The farther apart particles are, the greater their positional energy.
The faster a particle is moving, the greater the kinetic energy of the particle.
Temperature is associated with the motion of particles.
Temperature is associated with average Ep.
Positional energy is measured in ˚C.
Energy is measured in Joules.
Energy is measured in Newtons.
Energy is the ability to cause a change.
Energy is conserved in elastic collisions.
The first law of thermodynamics is often referred to as the law of conservation of mass.
Energy is defined as a push or a pull.
I think I have a good understanding of heat and temperature and how they relate to matter on the particle level.
