Answer:
You heat up a substance with larger specific heat capacity. Compared with a substance with a lower specific heat capacity, will its temperature will rise. Because, a substance with a lower specific heat capacity requires less heat energy to increase it temperature as compared to the substance with larger specific heat capacity.
The temperature of a different substances rises when we supply heat to it. If we supplied the same amount of heat to two different kinds of solid then rise in temperature may be different in both the solids. So, depending upon the nature of the solid, the rise in temperature varies for different kind of solids. This phenomenon is known as Specific heat Capacity.
In other words specific heat of a solid or liquid is the amount of heat that raises the temperature of a unit mass of the solid through 1° C. We symbolise it as C. In S.I unit, it is the amount of heat that raises the temperature of 1 kg of solid or liquid through 1K. If the amount of heat, ∆Q, required to raise the temperature of mass M through ∆T, then the formula for specific heat is given by:
C= ∆Q/m*∆T or ∆Q=m C ∆T.

16. What is the specific heat capacity of a substance if 24100 J are needed to change the temperature of it from 25.0 °C to 250.0°C? 9.18 x 10, 0.918 1.02 x 10 1.02
Calculating specific heat capacity A constant-pressure calorimeter is often used to find the specific heat capacity of a substance if it is not known. A known mass of the substance can be heated and added to water of known mass and initial temperature. Since the specific heat capacity of water is known ( C s,water =4.184J/(g⋅ ∘ C)) , the amount of heat transferred to the water can be calculated by measuring the final temperature of the mixture at thermal...

Consider the following data for an unknown substance X: AHvap = 21.00 kJ/mol Specific heat capacity of liquid = 2.40 J/g. °C Boiling point = 70.0°C Molar mass=92.00 g/mol When the temperature of 1.000 mole of X(g) is lowered from 94.0°C to form X(1) at 46.0°C, 29.97 kJ of heat is released. Calculate the specific heat capacity of X(9). Specific heat capacity = J/g. °C Submit Answer Try Another Version 5 item attempts remaining
The value of the heat capacity for a substance depends on whether it’s measured under constant pressure conditions or constant volume conditions. The constant-pressure molar heat capacity is given by = (dq/dT)P and the constant-volume heat capacity is given by = (dq/dT)V Note that we use d instead of because q is not a state function of temperature, volume, and pressure; its value depends on how we execute the process. Here are several questions regarding heat capacity. a. When we...
claculate the specific heat constant of an unknown substance if the system has a mass of 100g and the temperature rise is 2 C after releasing 0.45 kilocalories of heat.
5. Because of the high specific heat capacity of water compared to that of soil, a large lake takes longer to heat in the summer than an equivalent area of land. This effect moderates the temperature along the lakeside. But how does the cooler lake keep lakeside communities cooler, i.e. what is the mechanism of energy transfer? (0.5 mark)
