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.
At what temperature does aluminum turn into a solid? The scientific standard typically refers to the state change you refer to in terms of going up, so you need to know the melting point of aluminum to know when it becomes solid â¦ , which is 933.47 Kelvin (660.32Â°C or 1220.58Â°F).luminum burns at over 4,100 K (6920Â°F), which is why it is used as a component of some solid rocket fuels. When it burns, it produces Al2O3 (alumina). Wow!
