The planet closest to the sun; Mercury.
Answer:
Seismic waves are mechanical waves because they travel through the medium of the Earth.
Explanation:
Answer: Hence, the final temperature is 350 K
Explanation :
To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,

where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:

Putting values in above equation, we get:

Hence, the final temperature is 350 K
Out of the choices given, igniting the gas-air mixture supplies the heat for the hot reservoir in a car's engine. The correct answer is C.
