What the heck is the heat equation?

Click For Summary
The heat equation relates the amount of heat transferred to the specific heat capacity, mass, and temperature change of a material. It is expressed as Q = mcΔt, where Q is the heat transferred, m is the mass, c is the specific heat capacity, and Δt is the temperature change. Understanding this equation is crucial for comparing temperature changes in different metals based on their specific heat capacities. The discussion highlights the confusion around the equation and seeks clarification for its application in a practical scenario. Mastering the heat equation is essential for successfully completing related assignments.

My professor asked us to use the heat equation to compare temperature change with the specific heat of three metals. I have no idea of what the heat equation is. I read a little bit about it on Wikipedia, but the equation there makes no sense to me. I'd really appreciate if anyone could help me out with this. Thanks!

I'm guessing he/she means the equation that relates temperature change to specific heat capacity, mass and quantity of heat.
Q=mct
Q is amount of heat transferred (J)
c is specific heat capacity of the material
m is mass of material
t is temperature change (K or Celsius)
Does that help?
 
Thread 'Correct statement about size of wire to produce larger extension'

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
