The amount of heat needed to raise 2.0 kg of a substance by 80 K is 33 kJ. What is the specific heat of the substance?

Asked by taroeseler

Answer (2)

The specific heat of the substance can be calculated using the given heat energy transfer, mass, and temperature change. By applying the formula Q = m x c x K, the specific heat is found to be 206.25 J/kgK.
To determine the specific heat of the substance based on the given information, we can use the formula for heat energy transfer (Q), where Q = mass (m) x specific heat (c) x change in temperature (K)
We are given:
Plugging these values into the formula, we get: Q = m x c x K 33,000 J = 2.0 kg x c x 80 K c = Q / (m x K) c = 33,000 J / (2.0 kg x 80 K) c = 33,000 J / 160 kgK c = 206.25 J/kgK
Therefore, the specific heat of the substance is 206.25 J/kgK.

The specific heat of the substance can be calculated using the formula Q = mcΔT. In this case, the specific heat comes out to be 206.25 J/(kg·K).
