WebWhen a substance changes state, the number of molecules in that substance doesn’t change and so neither does its mass\n \n; This is known as conservation of mass \n \n \n; During a change of state the internal energy does change\n \n; Internal energy increases with increase in temperature (from solid to gas); \n \n \n WebEnergy must be transferred from a substance to the environment for these changes of state to happen. This is because forces of attraction form between the particles. Predicting a …

WebWhat is the energy change when a 2 kg glass window cools from 20°C to 10°C on a summers evening? c of Glass = 670 J/kg/°C. Change in temperature = 10 - 20 = -10°C. Δ__Q = m c __ΔΘ = 2 x 670 x -10 = -13,400 Joules. Specific Latent Heat.
