Apologies for the bump, but is anybody able to give me any kind of direction as to how I can go about solving my problem?

Hi, I am trying to calculate the amount of heat required to raise the temperature of a rubber sphere by 20 degree's Celcius within 10 seconds. The rubber sphere will be heated via radiation in a closed system. I have calculated the specific heat capactity, by using the formula q =...

It would seem that I could use Newton's law of cooling to calculate the time it would take to heat the object. Can anybody please verify?

q = mc (Tf-Ti) It roughly came to about 1100 Joules Are you saying that I need 1100 Joules in order to raise the temperature of the object with 1 degree celcius? Or does the formula mean that I need 1100 Joules in order to raise the temperature to the desired temperature?

Hi, I have a small rubber object that I want to heat to a particular temperature. I have done some research and I have found a formula to determine the heat capacity that I need in order to reach the specified temperature. However, the formula does not tell me : 1.) How long will it...
