Answer #1

Specific heat capacity can be determined by the formula Q = msT

Where Q is the amount of heat exchanged, m is the mass , s is the specific heat capacity, T is the change in temperature.

As we can see that if some measurement error is present in measurement of temperature and it changes the value by x celsius the difference of the temperature values will cancel out this error and thus our T value will have little to no error present but this is not the case with the measurement of mass. So, the errors in measurement of mass will have more effect on the specific heat capacity value as compared to errors in measurements of temperature.

What is the difference between heat capacity and specific heat? The heat capacity depends on the mass of the material, the specific heat does not. The specific heat depends on the mass of the material, the heat capacity does not. There is no difference. The specific heat refers to the amount of heat released or absorbed when a material changes state, the heat capacity refers to the amount of heat a material can store.

Specific Heat The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temperature. In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. Note the difference between the terms molar heat capacity, which has units of J/(mol⋅∘C), and specific heat, which has...
