Calculations for raising temperature in specific amount of time

Click For Summary
SUMMARY

The discussion focuses on calculating the heat required to raise the temperature of a rubber sphere by 20 degrees Celsius in 10 seconds using radiation in a closed system. The user has correctly identified the formula for heat transfer, q = m x Cg x (Tf - Ti), to determine the specific heat capacity. However, the user seeks guidance on how to calculate the time required for the sphere to reach the desired temperature, indicating a need for further exploration of heat transfer dynamics and radiation principles.

PREREQUISITES
  • Understanding of thermodynamics principles
  • Familiarity with specific heat capacity calculations
  • Knowledge of heat transfer methods, particularly radiation
  • Basic mathematical skills for applying formulas

Hi,

I am trying to calculate the amount of heat required to raise the temperature of a
rubber sphere by 20 degree's celsius 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 = m x Cg x (Tf - Ti)

However, it does not tell me how long it will take for the sphere to reach
the desired temperature.

Disclaimer : I am not a student and this is not a homework question.

Regards,
