Q1:
Two samples of water are at different temperatures. A 2 L sample is at 40°C, while a 1 L sample is at 70°C (Show ALL work and Units).

Q2:
The particles of which sample have a larger average kinetic energy (Show ALL work and Units)?

Q3: The water samples are mixed. Assuming no heat loss, what will be the temperature of the 3 L of water (Show ALL work and Units)?
