Ch. 5 Temperature and Heat (incomplete)

Question 1

the net flow of energy between two objects due to a temperature difference

Answer 1

heat

Question 2

the relative measure of the kinetic energy of an object’s particles

Answer 2

temperature

Question 3

the change in an object’s dimensions due to temperature

Answer 3

thermal expansion

Question 4

the heat required to raise one pound of water one Fahrenheit degree (unit often found used with hot water heaters and air conditioners)

Answer 4

BTU (British thermal unit)

Question 5

the heat required to raise one gram of water one Celsius degree

Answer 5

calorie

Question 6

food calorie

is 1000x a regular calorie unit

Answer 6

Calorie (“big C calorie”)

Question 7

the heat required to raise one gram of material one Celsius degree

Answer 7

specific heat capacity

Question 8

specific heat capacity for water

Answer 8

c = 1.00 cal/g ℃

Question 9

steam above 100 ℃

Answer 9

superheated steam

Question 10

ice below 0 ℃

Answer 10

sub-cooled ice

Question 11

the amount of moisture in the air compared to how much the air can hold at that temperature

Answer 11

relative humidity

Question 12

“latent” heat in this context means…

Answer 12

“hidden”, because the thermometer doesn’t see this heat flow

Question 15

equation: ideal efficiency

Answer 15

(insert LaTeX here) important: in this equation the temperatures must be in Kelvin; always convert from Celsius (TK = TC + 273.15)
