Answer:
156.67 m/s
0.45676 times the speed of sound
Explanation:
Distance from the ground = 23.5 km = 23500 m
Time taken by the blast waves to reach the ground =
Spedd of the wave would be
The velocity of the blast wave is 156.67 m/s
v = Velocity of sound = 343 m/s
The blast wave is 0.45676 times the speed of sound
<u>Answer:</u> The change in entropy of the given process is 1324.8 J/K
<u>Explanation:</u>
The processes involved in the given problem are:
Pressure is taken as constant.
To calculate the entropy change for same phase at different temperature, we use the equation:
.......(1)
where,
= Entropy change
= specific heat capacity of medium
m = mass of ice = 0.15 kg = 150 g (Conversion factor: 1 kg = 1000 g)
= final temperature
= initial temperature
To calculate the entropy change for different phase at same temperature, we use the equation:
.......(2)
where,
= Entropy change
m = mass of ice
= enthalpy of fusion of vaporization
T = temperature of the system
Calculating the entropy change for each process:
- <u>For process 1:</u>
We are given:
Putting values in equation 1, we get:
- <u>For process 2:</u>
We are given:
Putting values in equation 2, we get:
- <u>For process 3:</u>
We are given:
Putting values in equation 1, we get:
- <u>For process 4:</u>
We are given:
Putting values in equation 2, we get:
- <u>For process 5:</u>
We are given:
Putting values in equation 1, we get:
Total entropy change for the process =
Total entropy change for the process =
Hence, the change in entropy of the given process is 1324.8 J/K
