Calculate the energy required to heat 541.0mg of mercury from 11.4°C to 16.6°C. Assume the specific heat capacity of mercury under these conditions is 0.139 J·g^−1K^−1. Be sure your answer has the correct number of significant digits.

Explanation:

Hello!

In this case, since the equation that allows us to compute the energy required for such temperature increase is:

Whereas m is the mass, C the specific heat and T2 and T1 the final and initial temperature respectively; thus, by plugging in the given data, we obtain the following energy with consistent units and significant figures:

Considering that the specific heat can be used by unit of °C or K because their difference is equivalent.

Best regards!

it is a good conductor
