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?
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?
- 50 °C
- 100 °C
- 35 °C
50 g of iron at 100 °C goes into 500 g of water at 20 °C. Which ends closer to its starting temperature, Kira?
- The iron
- They change equally
- The water
Why does the water never reach the hot metal's starting temperature, Luz?
- The metal cools as the water warms
- Water can't get hotter than 30 °C
- The metal keeps its heat
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
- Disagree: heat flows from the drink to the ice
- Agree: ice gives off its heat
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
Pia says the hot metal and the water end at different temperatures. Agree or disagree?
- Disagree: they end at one temperature
- Agree: water stays colder than metal
- Agree: the metal stays hotter than the water
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
Why is water used to soak up the heat in a calorimeter, Tala?
- It has no specific heat
- It can't change temperature
- Its specific heat is known
A sealed steel calorimeter's case absorbs 893 J for each °C it warms. Why is this counted, Zee?
- Some heat warms the case, not the water
- It changes the water's mass
- The steel case makes extra heat of its own
