In the laboratory, a student finds that it takes 44.1 Joules to increase the temperature of 11.3 grams of gaseous krypton from 20.5 to 37.6 degrees Celsius.

The specific heat of krypton she has measured is _____ J/g · °C.

Answer :

Final answer:

The specific heat of krypton, calculated from the provided information using the formula for heat, is approximately 0.23 J/g·°C.

Explanation:

To find the specific heat of krypton, we can use the formula for heat, Q, which is: Q = mcΔT, where m is the mass, c is the specific heat, and ΔT is the change in temperature. We're looking for c, so we rearrange the formula to: c = Q/(mΔT).

By substituting the given values into the formula, we get: c = 44.1 Joules / (11.3 grams * (37.6 - 20.5) degrees Celsius), which simplifies to: c = 44.1 J / (11.3 g * 17.1 °C).

Therefore, the specific heat of krypton this student measured is approximately 0.23 J/g·°C.
