Describe how to find the volume of an irregular solid.
Use a balance to measure the length, width and height of the object and multiply them to find the volume.
Partially fill a measuring cylinder. Measure the volume and then calcualte the increase in volume when the object is added.
Partially fill a measuring cylinder, add the object and measure the volume in the measuring cylinder.
Use a balance to measure the mass and use this to calculate volume.
What is the internal energy of a substance?
The total kinetic energy and thermal energy stored inside a system by the particles (atoms and molecules) that make up the system.
The total kinetic energy and elastic energy stored inside a system by the particles (atoms and molecules) that make up the system.
The total kinetic energy and potential energy stored inside a system by the particles (atoms and molecules) that make up the system.
The total thermal energy and potential energy stored inside a system by the particles (atoms and molecules) that make up the system.
The symbol equation that relates the change in thermal energy of a system is ∆E = m c ∆θ. What does c represent?
Specific Heat Cpacity
Energy tranferred
Mass
Change in temperature
What is the specific heat capacity of a substance?
The energy needed for 1kg of a substance to change state is called latent heat.
The energy needed for 1kg of a substance to change state is called specific heat capacity.
The amount of energy required to raise the temperature of 1 kg of the substance to its boiling point.
The energy required to raise the temperature of 1 kg of the substance by 1 °C.
A solid object has a very large specific heat capacity. What does this mean?
A large amount of energy is needed to make the object increase in temperature.
A large amount of energy is needed to make the object melt.
A small amount of energy is needed to make the object increase in temperature.
A small amount of energy is needed to make the object melt.
A substance has a:
• melting point of 98 °C
• boiling point of 883 °C
What is the state of the substance at 20 °C?
Gas
Solid
Liquid
A substance has a:
• melting point of 98 °C
• boiling point of 883 °C
What is the state of the substance at 900 °C?
Gas
Solid
Liquid
When a substance is being heated and changing state the energy supplied changes...
the internal energy and the temperature.
the temperature but not the internal energy.
the internal energy but not the temperature.
What is the word equation for the energy for a change of state?
energy for a change of state = weight ×specific heat capacity×temperature change
energy for a change of state = mass × specific latent heat
energy for a change of state = mass×specific heat capacity×temperature change
energy for a change of state = weight × specific latent heat

A solid is heated from room temperature. The graph shows how its temperature changes with time as it is heated constantly. Between which labelled points on the graph is the substance partly solid and partly liquid?
between P and Q
between Q and R
between R and S
between S and T

How does the particle model of matter explain gas pressure?
Gas molecules are in constant random motion
When a molecule collides with a surface it exerts a force on the surface as it changes its direction/momentum.
When molecules collide with the surface they change energy, creating a force.
All of the above
