WebThe specific heat of copper is 0.09 BTU/lb. 10 lb x 50 degrees F x 0.09 BTU/lb = 45 BTU. How do the freezing point of water and absolute zero compare? The freezing point of water is a higher temperature than the absolute zero. Refrigerant in the evaporator coil of an air conditioner changes from a liquid to a gas when hot air passes over it. Web3 jun. 2024 · 1020 btu x 1.0177 yields a btu value of 1038 btu at the dry base also important: measuring a sample gas at a certain base of measurement does not mean that the sample gas is at those conditions it means that the btu value of that gas is being measured as if the sample gas were at those conditions Websaturated liquid at 80°F is 33.109 Btu/lb. At 20°F, it is 15.837 Btu/lb. Therefore, to cool 1 lb of R-22 satu-rated liquid from 80°Fto 20°F requires removing 17.272 Btu/lb (33.109 – 15.837). This difference is about the same whether heat content is based on 0°F, 40°F, –100°F, or even absolute zero. tryhackme advent 2022 day 23
