A 200 g copper block, c = 0.385 J/(g·°C), warms from 22 °C to 72 °C. How much heat does it absorb, Bo?
A 502 g iron block, c = 0.449 J/(g·°C), warms from 25 °C to 250 °C. How much heat does it absorb, Esme?
3.
Water cools from 80 °C to 30 °C. Is its q positive or negative, Jun?
- Positive: it loses heat
- Negative: it loses heat
- Zero: it is still water
4.
A sample cools from 85 °C to 21 °C. What is ΔT, Kira?
- 64 °C
- −64 °C
- 106 °C
5.
A sample's temperature rises. What sign does q have, Luz?
- Positive
- Negative
- Zero
6.
Which rearrangement of q = m × c × ΔT gives ΔT, Milo?
- ΔT = q × m × c
- ΔT = q ÷ (m × c)
- ΔT = m ÷ (q × c)
7.
Which rearrangement of q = m × c × ΔT gives m, Noah?
- m = c ÷ (q × ΔT)
- m = q × c × ΔT
- m = q ÷ (c × ΔT)
8.
Which rearrangement of q = m × c × ΔT gives c, Pia?
- c = ΔT ÷ (q × m)
- c = q × m × ΔT
- c = q ÷ (m × ΔT)
9.
Twice the mass of water is warmed by the same ΔT. How much heat does it take, Tala?
- Half as much
- Twice as much
- The same amount
10.
Equal masses of water and iron get equal heat. How do their temperature rises compare, Zee?
- Water's rises about 9 times more
- Iron's rises about 9 times more
- They rise by the same amount

Heat, mass, temperature change and specific heat. Every version has 10 questions, and the answer key prints on the second page.

I can use q = m × c × ΔT with ΔT = final − initial, including negative q for cooling.
I can rearrange it for ΔT, m or c.
I can find a specific heat from data and match it to a table.
I can explain why water warms slowly and metals quickly.

Standard: HS-PS3-1

heat, q: Energy moving because of a temperature difference, in joules

specific heat, c: Heat to warm 1 g by 1 °C, in J/(g·°C)

ΔT: Final temperature − initial temperature

absorb: Take in heat; q positive

release: Give out heat; q negative

Your child multiplied mass by temperature change and left out the specific heat. q = m × c × ΔT needs all three.

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

Your child divided the heat by the mass only. Specific heat is per gram and per degree, so divide by m × ΔT.

What is the most common mistake with heat, mass, temperature change and specific heat?

Your child multiplied mass by temperature change and left out the specific heat. q = m × c × ΔT needs all three.
