Web20 feb. 2024 · Because the density of water is 1000kg / m3, one liter of water has a mass of 1 kg, and the mass of 0.250 liters of water is mw = 0.250kg. Calculate the heat transferred to the water. Use the specific heat of water in Table 14.2.1 Qw = mwcwΔT = (0.250kg)(4186J / kgoC)(60.0oC) = 62.8kJ. Calculate the heat transferred to the … WebThe heat which is generated by the cells in the body is transferred to air or water which is flowing over the skin. 4. Air-Conditioner. On a hot summer day, air-conditioners are used constantly. The process of cooling air in air-conditioners employs the very principle of convection. The air which is cold is released by the air-conditioners.
