Answer:
The work done by the gas is 117,300 Joules.
Explanation:
Pressure applied on the gas , P= 102.0 kPa = 102000 Pa ( 1kPa = 1000 Pa
Change in volume of the gas ,ΔV=
Here the work is done by system so, the value of work done will be negative.
The work done by the gas is 117,300 Joules.
<u>Answer:</u> The final temperature of the mixture is 51.49°C
<u>Explanation:</u>
When two samples of water are mixed, the heat released by the water at high temperature will be equal to the amount of heat absorbed by water at low temperature
The equation used to calculate heat released or absorbed follows:
......(1)
where,
q = heat absorbed or released
= mass of water at high temperature = 140 g (Density of water = 1.00 g/mL)
= mass of water at low temperature = 230 g
= final temperature = ?°C
= initial temperature of water at high temperature = 95.00°C
= initial temperature of water at low temperature = 25.00°C
c = specific heat of water= 4.186 J/g°C
Putting values in equation 1, we get:
Hence, the final temperature of the mixture is 51.49°C
