Physics latent heat

Webb10 juli 2024 · Latent heat is measured in units of J/kg. Both L f and L v depend on the substance, particularly on the strength of its molecular forces as noted earlier. L f and L … WebbThe specific latent heat of vaporization of water is 2 x 10 6 J kg–1. (2 marks) (ii) Using the data and the formula in Table 5, estimate the increase in temperature of the air in the room, assuming that all the energy released in Part B is used to raise the temperature of the air inside the room.

Webb12 nov. 2024 · When ice melts into water that takes energy, when the same mass of water freezes that releases the same amount of energy. So here we have ice at a cold temperature so we need to raise it up to 0 degrees, we can work out how much energy is needed by Q=mc \delta T. This is the energy we need. Webbheat capacity c of water is 4.20 J g–1 °C–1. In order to calculate the specific latent heat L of ice, consider the heat balance where: heat lost by cooling water = heat gained by ice and warming melted ice m w × c × (θ 1 – θ 2) = (m i × L) + (m i … http://misssugarscience.weebly.com/uploads/9/7/0/3/97036086/10_-_shc_and_slh_practice.pdf handmaid\u0027s tale season 4 channel 4
