1.2 × 10⁴ cal
Explanation:
Given data
- Mass of water (m): 300 g
- Initial temperature: 80 °C
- Final temperature: 40°C
We can calculate the heat released by the water () when it cools using the following expression.
where
c is the specific heat capacity of water (1 cal/g.°C)
According to the law of conservation of energy, the sum of the heat released by the water () and the heat absorbed by the reaction (
) is zero.

Explanation:
Given
(a) to (d)
Required
Determine whether the given parameters can calculate the required parameter
To calculate either Density, Mass or Volume, we have
(a) 432 g of table salt occupies 20.0 cm^3 of space
Here, we have:
The above can be used to calculate Density as follows;
(b) 5.00 g of balsa wood, density of balsa wood : 0.16 g/cm^3
Here, we have:
This can be used to solve for Volume as follows:
(c) 32 cm^3 sample of gold density of 19.3 g/cm^3
Here, we have:
This can be used to calculate Mass as follows:
(d) 150 g of iron, density of Iron = 79.0 g/cm^3
Here, we have
This can be used to calculate volume as follows:
