Module #2: Energy, Heat, And Temperature

Question 1

Work

Answer 1

The force applied to an object times the distance that the object travels parallel to that force

Question 2

Heat

Answer 2

Energy that is transferred as a consequence of temperature differences

Question 3

The first law of thermodynamics

Answer 3

Energy cannot be created or destroyed. It can only change form.

Question 4

Potential energy

Answer 4

Energy that is stored

Question 5

Kinetic energy

Answer 5

Energy that is in motion

Question 6

Energy

Answer 6

The ability to do work

Question 7

Calorie (cal)

Answer 7

The amount of heat necessary to warm one gram of water one degree Celsius

Question 8

Specific heat

Answer 8

The amount of heat necessary to raise the temperature of one gram of a substance by 1 degree Celsius

Question 9

What is the specific heat of water?

Answer 9

1.000 cal/g. • C - OR - 4.184 J/g. • C

Question 10

1 calorie = how many Joules?

Answer 10

4.184 joules

Question 11

Kelvin = Celsius + ?

Answer 11

Kelvin = C + 273.15

Question 12

C = ? F

Answer 12

Celsius = 5/9(F-32)

Question 13

In the equation Q = M • (C) • 𝚫 T, what do the letters stand for?

Answer 13

Q = amount of heat absorbed or released, M = mass of object, C = specific heat of object, and Delta T = change in temperature

Question 14

How is 𝚫 T (change in temperature) represented

Answer 14

𝚫T = T_final - T_initial
