Practise MYP Physics questions on 2.5 Thermal Physics and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
Block X and Block Y are made of the same metal and are both at . Block X has a mass of and Block Y has a mass of . If both are placed in the same room at , which block will reach thermal equilibrium with the room first?
For an ideal gas, the pressure would theoretically drop to zero at a temperature of __________ Kelvin.
Substance A has a specific heat capacity of and Substance B has a specific heat capacity of . If of each substance is used to absorb of heat, which substance will show the smallest increase in temperature?
According to the particle model, what characterizes the behavior of particles in a liquid state?
Why does a tile floor feel colder to bare feet than a carpeted floor, even if both have been in the same room at for several hours?
It depends on the specific heat capacity of the metal

It depends on their initial temperatures
They will both show the same increase
They are locked in a fixed lattice and can only vibrate.
They remain close together but possess enough energy to move past one another.
They are far apart and move independently with no attractive forces.
They are highly compressible because of the large empty spaces between them.
The carpet contains more total thermal energy than the tile.
The tile reflects more thermal radiation than the carpet.
The tile conducts heat away from the feet faster than the carpet.
The tile is at a lower temperature than the carpet.
