thermal energy

Question 1

thermal energy

Answer 1

sum of the kinetic and potential energy of the particles that make up an object

Question 2

specific heat

Answer 2

amount of heat needed to raise the temperature of 1kg of a material 1 degree C

Question 3

temperature

Answer 3

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

Question 4

heat

Answer 4

energy that is transfered between objects due to a temperature difference between those objects

Question 5

conduction

Answer 5

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

Question 6

convection

Answer 6

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

Question 7

radiation

Answer 7

transfer of energy by electromagnetic waves

Question 8

thermal insulator

Answer 8

a material through which thermal energy moves slowly

Question 9

solar collector

Answer 9

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

Question 10

thermodynamics

Answer 10

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

Question 11

first law of thermodynamics

Answer 11

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