Heat (Heat & thermodynamics)
Q = mcΔT
Where: ΔT = change in temperature (K), Q = heat (J) / charge (C), c = specific heat (J/kg·K) / speed of light, m = mass (kg)
Solved example
Given: Delta_T = 7, c = 5, m = 10
Find: Q (heat (J) / charge (C))
- Formula: Q = ΔT·c·m
- Substitute the values: Q = 10·5·7
- Result: Q = 350 J
Answer: Q = 350 J
