zalisa [80]
I don't have a graph but here's what I think. The relationship is that the volume will change depending on the temperature. So think of water for an example. The volume of it will stay the same at room temperature, but if you put a glass of it in the freezer for a few hours, take it out, measure the volume, the volume would have changed greatly. Or heating and evaporating the water will do the same.

A 100-gram sample of material requires 1220 calories of heat energy to raise its temperature from 20 0C to 80 0C. What is the sp
SashulF [63]

Taking into account the definition of calorimetry, sensible heat and latent heat, the specific heat capacity of the material is 0.203 \frac{calories}{gC}.

<h3>Calorimetry</h3>

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

The amount of heat a body receives or transmits is determined by:

Q = c× m× ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

<h3>Specific heat capacity of the material</h3>

In this case, you know:

  • Q= 1220 calories
  • c= ?
  • m= 100 g
  • ΔT=Tfinal - Tinitial= 80 C - 20 C= 60 C

Replacing in the definition of amount of heat:

1220 calories= c× 100 g× 60 C

Solving:

c= 1220 calories÷ (100 g× 60 C)

<u><em>c= 0.203 </em></u>\frac{calories}{gC}

Finally, the specific heat capacity of the material is 0.203 \frac{calories}{gC}.
