Answer:
38.3958 °C
Explanation:
As,
1 gram of carbohydrates on burning gives 4 kilocalories of energy
1 gram of protein on burning gives 4 kilocalories of energy
1 gram of fat on burning gives 9 kilocalories of energy
Thus,
27 g of fat on burning gives 9*27 = 243 kilocalories of energy
20 g of protein on burning gives 4*20 = 80 kilocalories of energy
48 gram of carbohydrates on burning gives 4*48 = 192 kilocalories of energy
Total energy = 515 kilocalories
Using,
Given: Volume of water = 23 L = 23×10⁻³ m³
Density of water= 1000 kg/m³
So, mass of the water:
Mass of water = 23 kg
Initial temperature = 16°C
Specific heat of water = 0.9998 kcal/kg°C
Solving for final temperature as:
<u>Final temperature = 38.3958 °C </u>
Answer:
The value is

The initial temperature of the fluorocarbon gas is
The final temperature of the fluorocarbon gas is
The initial pressure is
The final pressure is
Generally the equation for adiabatically reversible expansion is mathematically represented as
Here R is the ideal gas constant with the value
So
=>
Generally adiabatic reversible expansion can also be mathematically expressed as
=>
=>
=>
So
