Specific heat of brass cal/g*c
Web15.5°C. Hence, by definition, water has a specific heat of 1 cal/g°C over that range of temperature. The specific heats of other materials are determined by comparing with that of water and are tabulated for many common materials. For instance, the accepted value of the specific heat of brass is g C cal 0. 0925 o Webcp = specific heat (kJ/kg K, kJ/kg oC) dt = temperature difference (K, oC) Example - Required Heat to increase the Temperature in a Piece of Oak If 10 kg of oak is heated from 20 oC to 50 oC - a temperature difference 30 oC (K), the heat required can be calculated as q = (2 kJ/kg K) (10 kg) (30 oC) = 600 kJ

WebJan 7, 2024 · the magnitude of the temperature change (in this case, from 21 °C to 85 °C). The specific heat of water is 4.184 J/g °C (Table 12.3.1 ), so to heat 1 g of water by 1 °C requires 4.184 J. We note that since 4.184 J is required to heat 1 g of water by 1 °C, we will need 800 times as much to heat 800 g of water by 1 °C.
