, Liquid R - 
, Liquid S - 
Explanation:
a) The specific heat capacity means the amount of heat needed by a unit mass of a material to increase its temperature in one unit.
b) Let suppose that heat transfer rates between liquids and surroundings are stable. The quantity of the heat released is determined by the following expression:
(1)
Where:
- Mass of the liquid, in kilograms.
- Specific heat capacity, in joules per kilogram-degree Celsius.
- Initial temperature of the sample, in degrees Celsius.
- Freezing point, in degrees Celsius.

Answer: The center of gravity is 1.1338 m away from the left side of the barbell
Explanation:
Length of the barbell = 1.90 m
The distance center of gravity from left = x
Mass on the left side = 25 kg
The distance center of gravity from right = 1.90 - x
Mass on the right side = 37 kg
At the balance point: 
The center of gravity is 1.1338 m away from the left side of the barbell
