Answer:
Thermodynamics is usually defined as a branch of physics that deals with the study of the heat and various form of energy, and their interaction between the.
The first law says that heat appears as energy, and it cannot be produced and also cannot be demolished. It can only change from one form to another. This signifies that the total amount of energy present in the universe remains constant.
This first law can be mathematically represented as:
ΔU = Q - W
where ΔU = Changes occurring in the internal energy
Q = amount of heat added to the system
W = Amount of work done by the system
Hi!
<span>Acceleration is the rate of change of</span> velocity
Velocity is the rate of speed of an object
<span>sound waves are a type of wave sometimes called compression waves, vibrations with enough of an amplitude can compress and decompress the air adjacent to the object causing the waves to form.</span>
Using the pressure law (P1 x V1)/ T1 = (P2 x V2)/ T2 where P1= the initial pressure V1= initial volume T1= initial temperature and P2= the final pressure V2= the final volume T2 = the final temperature and temperature is always in kelvin
