1.) Identify two types of heat? One type of heat causes a change in temperature, the other type of heat causes a change of state.

Explanation:

Thermal Energy and Heat

Shards of ice fly from the sculptor’s chisel. As the crowd

looks on, a swan slowly emerges from a massive block of ice. As

the day wears on, however, drops of water begin to fall from the

sculpture. Drip by drip, the sculpture is transformed into a puddle of liquid water. What makes matter change from one state to

another? To answer this question, you need to think about the

particles that make up matter.

Energy Simply stated, energy is the ability to do work or cause

change. The energy of motion is called kinetic energy. Particles

within matter are in constant motion. The amount of motion of

these particles depends on the kinetic energy they possess. Particles

with more kinetic energy move faster and farther apart. Particles

with less energy move more slowly and stay closer together.

The total kinetic energy of all the particles in a sample of

matter is called thermal energy. Thermal energy, an extensive

property, depends on the number of particles in a substance as

well as the amount of energy each particle has. If either the

number of particles or the amount of energy in each particle

changes, the thermal energy of the sample changes. With identically sized samples, the warmer substance has the greater thermal energy.
