A metal piece of 59.7 g at 100 °C is placed in 60 g of water at 22 °C; both end at 28.5 °C. With water's c = 4.18, find the metal's specific heat, Ari?
A steel rod of 360 g at 248 °C is placed in 425 g of water at 24 °C; both end at 42.7 °C. With water's c = 4.18, find the steel's specific heat, Bo?
A metal piece of 50 g at 90 °C is placed in 100 g of water at 20 °C; both end at 26.8 °C. With water's c = 4.18, find the metal's specific heat, Esme?
4.
100 g of water at 80 °C and 300 g of water at 20 °C share heat in an insulated cup. What is the final temperature, Jun?
- 100 °C
- 35 °C
- 50 °C
5.
50 g of iron at 100 °C goes into 500 g of water at 20 °C. Which ends closer to its starting temperature, Kira?
- They change equally
- The water
- The iron
6.
Why does the water never reach the hot metal's starting temperature, Luz?
- The metal keeps its heat
- The metal cools as the water warms
- Water can't get hotter than 30 °C
7.
Milo says cold flows from an ice cube into a warm drink. Agree or disagree?
- Agree: cold moves out of the ice and into the drink
- Agree: ice gives off its heat
- Disagree: heat flows from the drink to the ice
8.
Noah says the cold pack's water cooled because cold spread from the solid into it. Agree or disagree?
- Agree: the water lost mass
- Agree: cold spread from the solid
- Disagree: heat left the water
9.
Pia says the hot metal and the water end at different temperatures. Agree or disagree?
- Agree: water stays colder than metal
- Disagree: they end at one temperature
- Agree: the metal stays hotter than the water
10.
In an exothermic run, some heat escapes to the air. Is the measured heat too high or too low, Ren?
- Too low
- Exactly right
- Too high

About this worksheet

Read calorimetry data: heat moves from hot to cold. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can say heat flows from hot to cold until both share one temperature.
I can use heat lost by the hot part = heat gained by the cold part.
I can find the water's heat from described data and give q its sign.
I can find a metal's specific heat from a described experiment and name what makes results too low.

Standard: HS-PS3-4

Words to know

calorimeter: An insulated container where heat exchange is measured

thermal equilibrium: The state where both parts share one temperature

heat gained: Positive q, as the temperature rises

heat lost: Negative q, as the temperature falls

insulated: Keeping heat from escaping

Common mistakes

Your child added the two temperatures. Equal masses of water share the heat evenly, so the final temperature is the average.

Your child used the final temperature instead of the change. ΔT = final − initial.

Your child used the metal's starting temperature, not its change. The metal cooled from its start to the final temperature.

Questions parents ask

What is the most common mistake with read calorimetry data: heat moves from hot to cold?

Your child added the two temperatures. Equal masses of water share the heat evenly, so the final temperature is the average.
