- Aluminum
- Copper
- Iron
Using the table, a metal's specific heat is measured as 0.38 J/(g·°C). Which metal is it most likely, Kira?
- Gold
- Copper
- Aluminum
Using the table, a metal's specific heat is measured as 0.45 J/(g·°C). Which metal is it most likely, Luz?
- Gold

Milo says a warm bath and a cup of the same water at the same temperature hold equal heat. Agree or disagree?
- Agree: water is water
- Disagree: the bath has more mass
- Agree: equal temperature means equal heat
Noah says warming 200 g of water by 10 °C takes the same heat as 100 g by 10 °C. Agree or disagree?
- Agree: water's c is the same
- Disagree: twice the mass, twice the heat
- Agree: the same ΔT means the same heat
Pia says a substance with a high specific heat warms up quickly. Agree or disagree?
- Agree: high c lets heat in faster
- Disagree: it warms slowly
- Agree: water warms faster than metals
6,270 J warms 50 g of water. By how much does its temperature rise, Tala?

- 0.03 °C
Which needs more heat to warm by 10 °C: 100 g of water or 500 g of iron, Zee?
- They need the same
- The 100 g of water
- The 500 g of iron
