# specific heat of graphite j/kg c

4184000 J Calculate the specific heat of a metal if 0.5 kg of the metal absorbs 9,000 J of heat as it warms by 10 ºC. The specific heat is the amount of heat energy per unit mass required to raise the temperature by one degree Celsius. Below this table is an image version for offline viewing.

The specific heat capacity of materials ranging from Water to Uranium has been listed below in alphabetical order. It is added to a container of water with 100.0 mL of water at 25 oC to cool off. Since the specific heat capacity is given in Joules / Celsius * grams, we must first convert the mole of Ag into grams: 1 mol Ag * (107.87 g / mol Ag) = 107.87 grams of Ag. The water in the cup rises to 80 oC. Its symbol is J/kg•°C. The specific heat capacity, c g, for graphite was hence obtained as c g = 707.8 J kg −1 K −1 with u c = 0.9 J kg −1 K −1 at 295.15 K. The main contribution to the uncertainty is in this case the possibility of residual heat loss. The specific heat capacity of graphite is 0.71 J/°C g. Calculate the energy required to raise the temperature of 34 kg graphite from 294 K to 348 K. J 1 Measurement of specific heat of graphite Aim: Estimation of the specific heat of graphite Apparatus: (i) Graphite sample, (ii) Heater filament, (iii) Stop watch (iv) Variac (variable transformer), (v) Voltmeter, (vi) Ammeter and (vii) Chromel (Nickel-Chromium alloy) Alumel Calculate the change in thermal energy of water in a pond if the water has a mass of 1,000 kg and a specific heat of 4184 J/(kg ºC) if the water cools by 1 ºC. Now we use the specific heat capacity to get the amount of energy required: 107.87 grams Ag (0.24 J / C*g)(1 C) = 25.88 Joules Free online specific heat capacity converter - converts between 20 units of specific heat capacity, including joule/kilogram/K [J/(kg*K)], joule/kilogram/°C [J/(kg*°C)], joule/gram/°C [J/(g*°C)], kilojoule/kilogram/K, etc. Also, explore many other unit converters or learn more about specific heat capacity unit conversions. Joule/Kilogram K : The joule per kilogram per kelvin is a SI derived unit of specific heat capacity. Suppose a steel bolt, with a mass of 95.00 g (specific heat = 450 j/kg oC) is heated to red-hot in a flame. What was the temperature of the bolt before it was added to the cup? Joule/Kilogram °C : The joule per kilogram per degree Celsius is a metric unit of specific heat capacity. Its symbol is J/kg•K.
