TK = 273 + T˚C

1

T˚C = 273 + TK

1

TK = 237 + T˚C

1

0 K = 273 ˚C

1

0 Kelvin is the lowest possible temperature.

1

It takes more energy to heat or cool a large sample of a substance than it does for a small sample of the substance.

1

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.

1

Boiling occurs when particles are able to escape from within the liquid.

1

Evaporation occurs when particles on the surface of the liquid escape into the surroundings.

1

Evaporation occurs at a variety of temperatures.

1

In order for a liquid to boil, the particles have to have enough energy to escape from the liquid.

1

When a solid is in the process of melting, the particles are moving faster.

1

When a solid is in the process of melting, the particles are moving farther apart.

1

As the temperature of a solid increases, the particles vibrate more energetically.

1

A 10.00 g sample of iron at 75˚C has more 'heat' than a 50.00 g sample.

1

Endothermic processes involve the loss of energy from the system.

1

Calories are a unit of thermal energy.

1

Heat is sometimes defined as the total amount (the sum) of kinetic energy in a system.

1

The boiling point of a substance (at a constant atmospheric pressure) is always the same.

1

On the particle level, energy is transfered by means of elastic collisions.

1

If two particles collide in an elastic collision, the faster particle will typically slow down and the slower particle will speed up.

1

The higher the temperature of 25.0 g of a substance, the smaller its density.

1

Heat rises.

1

Heat is technically defined as the flow of thermal energy.

1

The temperature of 10.0 g of boiling water is less than the temperature of 100.0 of boiling water.

1

Temperature is an extensive property.

1

Gases have a great deal of freedom of motion.

1

The higher the temperature of a substance, the greater the volume of the substance tends to be.

1

The higher the temperature of a substance, the faster the particles are moving.

1

The higher the temperature of a substance, the heavier the particles are.

1

Solids have a high Ep.

1

The farther apart particles are, the greater their positional energy.

1

The faster a particle is moving, the greater the kinetic energy of the particle.

1

Temperature is associated with the motion of particles.

1

Temperature is associated with average Ep.

1

Positional energy is measured in ˚C.

1

Energy is measured in Joules.

1

Energy is measured in Newtons.

1

Energy is the ability to cause a change.

1

Energy is conserved in elastic collisions.

1

The first law of thermodynamics is often referred to as the law of conservation of mass.

1

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.
