SUMMARY

The measurement of heat transfer from a heater to a solid can be calculated using the formula Q = (Mass of solid) * (Specific heat capacity of solid) * (Rise in temperature). This approach assumes that all energy from the heater, measured in watts (joules per second), is transferred to the solid without any losses to the environment. While this method is suitable for theoretical calculations, real-world applications must account for energy losses.

PREREQUISITES
  • Understanding of thermal energy and heat transfer principles
  • Basic knowledge of specific heat capacity
  • Familiarity with the concept of power in watts
  • Ability to perform calculations involving mass and temperature changes
NEXT STEPS
  • Research the concept of thermal energy transfer in real-world systems
  • Learn about specific heat capacity for various materials
  • Explore the effects of energy loss in heating systems
  • Study the principles of thermodynamics related to heat transfer
USEFUL FOR

Students in physics, engineers working with heating systems, and anyone interested in understanding the principles of heat transfer and energy conservation.

*eh hem*, this is my first post in this forum and i have a query on heat transfusion, i think i have the right forum though.

how do you measure the transfer of heat from a heater of certain watt's to a solid of certain mass?

thank you in advance,
ben

FIrst, you have to make a huge assumption that the "watts" (this is the power of the heater) is going entirely into the thing being heated, and none of the energy is leaking into the atmosphere or anything else. For beginner physics this is OK, although int he real world you can be guaranteed that some energy will go elsewhere.

So, since "watts" is the same thing as "joules per second", then you multiply "watts" times the number of seconds that heater is on. Heat is the transfer of thermal energy. Power times times equals energy.
 
well in a perfect system

energy lost by your heater = energy gained by the solid
Q = (Mass of solid)*(specific heat capacity of solid)*(rise in temp)
