WebSoil has an approximate specific heat of 800 J / kg °C. A farmer monitors both the soil temperature of his field and the temperature of a nearby pond as winter sets in. Will the field or the pond reach 0 °C first and why? The pond will reach 0 °C first because of water’s greater specific heat. WebThe temperature of the ice rises linearly, absorbing heat at a constant rate of 0.50 cal/g⋅ºC until it reaches 0ºC. Once at this temperature, the ice begins to melt until all the ice has melted, absorbing 79.8 cal/g of heat. The … WebOn theoretical grounds, the specific heat of dry ice will be smaller than that of water. If quantum effects are ignored, Each particle stores the same thermal energy. With CO2 and H2O, each molecule two substances would store equal additional amounts of thermal energy for every degree of added temperature. genshin terminology
