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?
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 water
- The iron
- They change equally
Why does the water never reach the hot metal's starting temperature, Luz?
- Water can't get hotter than 30 °C
- The metal cools as the water warms
- The metal keeps its heat
Noah says the cold pack's water cooled because cold spread from the solid into it. Agree or disagree?
- Disagree: heat left the water
- Agree: cold spread from the solid
- Agree: the water lost mass
Pia says the hot metal and the water end at different temperatures. Agree or disagree?
- Agree: the metal stays hotter than the water
- Agree: water stays colder than metal
- Disagree: they end at one temperature
In an exothermic run, some heat escapes to the air. Is the measured heat too high or too low, Ren?
- Too high
- Too low
- Exactly right
Why is water used to soak up the heat in a calorimeter, Tala?
- It can't change temperature
- It has no specific heat
- Its specific heat is known
A sealed steel calorimeter's case absorbs 893 J for each °C it warms. Why is this counted, Zee?
- The steel case makes extra heat of its own
- It changes the water's mass
- Some heat warms the case, not the water
