sending signals to muscles, causing them to contract, or to glands, causing. them to produce secretions. Neurons, or nerve cells, carry out the functions of the nervous system by. conducting nerve impulses.
Best Answer: Specific Heat is the energy required to raise EACH gram of a material by 1C. This is expressed in J/gC. The temperature change is 82.1C - 30.7C = 51.4C. The Aluminum weighs, not 1g, but 625g. m x c x Î´T = Q 29.5g x 0.45J/g/Â°C x (40 - 25Â°C) Î´T = 199.125 Joules (= 0.199kJ) of heat absorbed. (you can say 0.200kJ) If 8.4kJ was used as in your initial statement, to raise the temp. by 5Â°C, the mass of iron must have been much greater than 29.5g. or, 8.4kJ is an error. 29.5 x 0.45 x 5 = 66.4 kJ.
Introduction: The amount of heat energy that is required to raise the temperature of one gram of a substance by one degree Celsius is called the specific heat capacity, or simply the specific heat, of that substance. Water, for instance, has a specific heat of 1.0 cal / g â¢ C o. Remember that the heat gained by the water is equal to the heat lost by the metal, calculate the specific heat of the metal. 2  This is simply rearranging formula (3) from the introduction to solve for the specific heat of the metal, and plugging-in your data.
