Match the following

• volume

• the measurement of how tightly a material is packed together.  It is defined as the mass per unit volume

• temperature

•  is a measure of the average kinetic energy of all particles of an object or substance

• density

• the amount of space taken up by a three dimensional solid

• matter

• anything that has mass and takes up space

• mass

•  the amount of matter or substance that makes up an object. It is measured in units called kilograms,

This is the energy an object has because of the movement of its molecules; heat can be transferred from one object to another object (a)   ​

• thermal energy
• temperature
