Thermal Physics quiz for Singapore O-Level Physics (SEAB 6091) quiz

Solid

Liquid

Gas

They are the same in all states

The total thermal energy it contains

Its mass

The number of particles it has

The average kinetic energy of its particles

$252000\ \text{J}$

$126000\ \text{J}$

$63000\ \text{J}$

$84000\ \text{J}$

The energy supplied stops the particles moving

The energy supplied breaks bonds between particles rather than raising their kinetic energy

No energy is being supplied

The thermometer is faulty

Its low density

Its low boiling point

Its high specific heat capacity

Its high latent heat of fusion only

They are the same thing

Temperature is energy; heat is a number of particles

Heat is measured in degrees Celsius; temperature in joules

Heat is total thermal energy in joules; temperature is how hot something is

The particles gain energy and vibrate more, taking up more space

New particles are created

The particles shrink

The mass increases

Raise the temperature of one kilogram by one degree

Melt one kilogram of a solid without a temperature change

Boil one kilogram of a liquid

Cool one kilogram of a gas

Solid

Liquid

Gas

All expand equally

Changes colour with temperature

Becomes denser when heated

Evaporates when heated

Expands up the tube when heated

$0\,^{\circ}\text{C}$ and $100\,^{\circ}\text{C}$

$0\,^{\circ}\text{C}$ and $50\,^{\circ}\text{C}$

$32\,^{\circ}\text{C}$ and $212\,^{\circ}\text{C}$

$100\,^{\circ}\text{C}$ and $200\,^{\circ}\text{C}$

The drop has more thermal energy because it is hotter

The bucket can have more thermal energy despite its lower temperature

They must have equal thermal energy

Thermal energy depends only on temperature
