2 cards from this section. Quick, good the night before a test.
What is the principle of calorimetry?
Think about energy conservation.
What does Q represent in the equation Q = mcΔT?
It’s related to energy change.
What does the principle of calorimetry state?
Remember the energy balance when two bodies interact.
True or False: In a perfect calorimeter, heat can be lost to the environment.
Think about the design of calorimeters.
A 250 g piece of copper at 100°C is placed in 150 g of water at 20°C. Calculate the final temperature, assuming no heat loss.
You will need the specific heat capacities of both copper and water.
A mixture of ice and water is put together. If 100 g of ice at 0°C melts into water and the initial water at 20°C is 300 g, calculate the final temperature of the system once it reaches thermal equilibrium.
Apply the concept of latent heat in your calculations.
