How energy is transferred between states of matter

Solids - A  solid object is an object that can not be moulded or moved without being smashed or broken . But why can't it be moved ? . Well , the particles that are in a solid object are really close together . All the particles are hugging each other making it really strong . As the atoms of the solid gain energy of movement , the temperature increases . This process is called conduction .

Liquid and  Gas -   Liquid is a substance that flows freely. The consistency is just like water. The particles that are in liquid are close together just like solid , but are more apart . The particles are able to constantly shift and move around . This process is called  convection . Convection occurs when particles with a lot of heat take the place of the particles with less heat . Heat is transferred from hot places to cooler places by convection . Gas . Gas is a air like substance which expands to fill any available space . the particles in gas are very far apart . The particles are  able to have a lot of space . Just like liquid the particles with a lot of  heat take the place of the particles that have less heat . Liquid and gas have the same process called convection .

My Grandad

My  Grandad

Although he is old, he still has fun . His skin is beaten to a tan like old leather jacket . He has dark brown eyes that mischievously look at you . The hair is straight, tidy and clean . Commonly he would wear a plain T-shirt with comfy trousers .

Spinifex

          Spinifex

The wind lifts up the spinifex lightly . It tumbles round the sandy beach like a beach ball .

The dull brown stalk huddles in the middle like it's scared .

The spinifex camouflages itself in the soft light sand , but takes risks into darker wet sand or crashes into your sensitive feet .
