PPT-Temperature T determines the direction of heat transfer. Heat between two objects in contact

1 T 2 The most common is Celsius temperature scale T 0 o C is the melting point of ice and T 100 o C is the boiling temperature of water at atmospheric pressure Many properties of matter depend on temperature For most substances volume increases upon heating exception water near freezing point between 0. 4.1 ………….
