Question 1

Which of the following best describes the difference between temperature and heat?

Accepted Answer

Temperature is a measurement of the average kinetic energy of particles, while heat is the flow of thermal energy from a higher temperature object to a lower temperature object.

Question 2

Which container would have the greatest flow of thermal energy if placed in contact with another at a lower temperature?

Accepted Answer

A container with 120 g H$_2$O at 80$^	ext{o}$C

Question 3

What is the formula to convert Celsius temperature to Kelvin?

Accepted Answer

$K = C + 273.15$

Question 4

If the temperature is 45$^	ext{o}$C, what is the temperature in Kelvin?

Accepted Answer

$K = 318.15$

Question 5

Which equation correctly converts Celsius to Fahrenheit?

Accepted Answer

$F = 1.8(C) + 32$

Question 6

A scientist measures the temperature of a liquid as 53.3$^	ext{o}$C. What is this temperature in Fahrenheit?

Accepted Answer

$F = 127.94$

Question 7

At what temperature are the Celsius and Fahrenheit scales equal?

Accepted Answer

$-40$

Question 8

Which of the following is an example of heat transfer?

Accepted Answer

A metal spoon warming up when placed in hot soup

Question 9

If the melting point of phosphorus is 44.15$^	ext{o}$C, what is this temperature in Fahrenheit?

Accepted Answer

$F = 111.47$

Question 10

Which of the following statements about energy is correct?

Accepted Answer

Energy is the capacity to do work or produce heat.

Question 11

A patient’s body temperature is measured at 38.5$^	ext{o}$C. What is this temperature in Fahrenheit?

Accepted Answer

$F = 101.3$

Question 12

Which of the following is NOT a unit of temperature?

Accepted Answer

Joule (J)

Question 13

A sample of water is heated from 20$^	ext{o}$C to 80$^	ext{o}$C. Which statement best describes what happens?

Accepted Answer

The average kinetic energy of the water molecules increases.

Question 14

Which of the following best explains why heat flows from a hot object to a cold object?

Accepted Answer

Heat flows from higher temperature to lower temperature due to the difference in average kinetic energy.
