Match the following

• mass

• anything that has mass and takes up space

• matter

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

• density

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

• temperature

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

• volume

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

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
