What is meant by the fixed points of the scale of a liquid-in-glass thermometer?
the distance between one scale division and the next
the maximum and minimum depth to which the thermometer should be submerged in a liquid
the two agreed temperatures used for marking the temperature scale
the highest and lowest temperatures that the thermometer can record
Which quantity gives the thermal capacity of a beaker?

B
D
C
A long thin bar of copper is heated evenly along its length.
It becomes less heavy.
It becomes longer.
It becomes shorter.
It bends at the ends.
A solid object has a very large thermal capacity. What does this mean?
A large amount of energy is needed to make the object become hot.
A large amount of energy is needed to make the object melt.
A small amount of energy is needed to make the object become hot.
A small amount of energy is needed to make the object melt.
Which statement about evaporation is correct?
Evaporation causes the temperature of the remaining liquid to decrease.
Evaporation does not occur from a cold liquid near its freezing point.
Evaporation does not occur from a dense liquid, such as mercury.
Evaporation occurs from all parts of a liquid.
Which statement describes what happens as ice at 0°C starts to melt to become water?
Energy is absorbed and the temperature remains constant.
Energy is absorbed and the temperature rises.
Energy is released and the temperature remains constant.
Energy is released and the temperature rises.
What is Conduction?
When you heat fluid particles gain energy, so they move more and spread out.
particles are very close together, so they can transfer heat energy as they vibrate.
The particles between the Sun and the earth travel by conduction
the steady flow between the warm and cool sections of a fluid, such as air or water.
Which expression gives the specific heat capacity
B
A
C
D
Which of these is a fixed point on the Celsius scale?
room temperature
the temperature inside a BTS freezer
the temperature of pure melting ice
the temperature of MY HEART
In an experiment, a liquid is heated at a constant rate. The temperature of the liquid increases and eventually becomes constant. Which statement about the experiment is correct?
Boiling occurs at all temperatures but only on the liquid surface.
Boiling occurs throughout the liquid but only at the constant temperature.
Evaporation occurs throughout the liquid and at all temperatures.
Evaporation occurs only at the constant temperature and only on the liquid surface.
Which quantity gives the thermal capacity of a solid object?
the energy lost by radiation from the object in 1.0s
the energy needed to melt the object'S SURFACE XD.
the energy needed to raise the temperature of the object by 1.0°C
the total amount of thermal energy in the object
A liquid is at a temperature below its boiling point. The liquid is then heated so that it becomes a gas at a temperature above its boiling point. Which row correctly compares the liquid with the gas?
