Thermal Energy

Question 1

Thermal Energy

Answer 1

Sum of kinetic and potential energy of the particles that make up the object.

Question 2

Specific Heat

Answer 2

Amount of heat needed to raise the temperature of 1 kg of a material 1*C

Question 3

Heat

Answer 3

Energy that is transferred between objects due to temperature difference between those objects

Question 4

Conduction

Answer 4

Transfer of thermal energy by collisions between the particles that make up matter

Question 5

Convection

Answer 5

Transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another

Question 6

Radiation

Answer 6

Transfer of energy by electromagnetic waves

Question 7

Thermal Insulator

Answer 7

A material through which thermal energy moves slowly

Question 8

Solar Collector

Answer 8

Device used in an active solar heating system that transforms radiant energy from the sun into thermal energy

Question 9

Thermodynamics

Answer 9

Study of the relationship between thermal energy, heat, and work

Question 10

1st Law of Thermodynamics

Answer 10

If the mechanical energy of a system is constant, the increase in thermal energy of that system equals the sum of the thermal energy transfers into that system and the work done on that system

Question 11

2nd Law of Thermodynamics

Answer 11

That energy spontaneously spreads from regions of higher concentration to regions of lower concentration.

Question 12

Temperature

Answer 12

Measure of the average kinetic energy of all the particles that make up an object.
