Question 1 Report

A zinc has a heat capacity of 40 J/K, what is the mass of the zinc, given that the specific heat of zinc is 380 J/kg k
Answer Details
We can use the formula: heat capacity = mass x specific heat capacity to find the mass of the zinc. Rearranging the formula, we get: mass = heat capacity / specific heat capacity Substituting the given values, we get: mass = 40 J/K / 380 J/kg K mass = 0.1053 kg So, the mass of the zinc is approximately 0.11 kg. Therefore, the correct option is: - 0.11kg , 3, and 4 are not correct because they are different values and do not match the result of the calculation.
