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.
Press TEMP or TEMP/HOUR âupâ or âdownâ arrow pad to set a temperature other than 350Â°F (175Â°C) in 5Â°F (3Â°C) amounts. The bake range can be set between 170Â°F and 500Â°F (75Â°C and 260Â°C).When the oven temperature is greater than 170Â°F (77Â°C), no preheat conditioning time will be shown in the display. The preheat conditioning time will not change if the temperature is reset before the countdown time ends. 3. Press START.
