Thermal equilibrium and determining specific heat capacity
Answers are for parents and teachers.
1
Using the sample method: m_s = 0.3 kg of water, 20 °C → 22 °C. Heat received by the water (J)?
2520
2
If 400 g of water at 80 °C and 200 g at 20 °C are mixed, t (°C)?
60
3
Why is the outer vessel of a calorimeter made of a poor heat conductor?
To reduce heat loss to the surroundings.
4
Define thermodynamic equilibrium in your own words.
A state in which bodies have equal temperature and there is no net heat exchange between them.
5
A body with c = 450 J/(kg·K) is probably which material? (steel 460, copper 390, aluminium 890)
Steel (close to 460).
