Answer:
Explanation:
Machines simply make work easier to do. They increase the amount of force exerted on a body and also the distance through which the force is applied. Also, they can also change the direction through which force on them is applied in order to produce much more work.
Work done = force x distance
The input force in a machine is attenuated to yield even more force. This is the purpose of designing a simple machine. When the force increases, more work would be produce with our little effort applied on the body.
Work done is a function of the force applied on a body and the distance through which it moves.
Answer:
389.78681 K
Explanation:
= Initial pressure = 55.1 mmHg
= Final pressure = 1 atm = 760 mmHg
= Boiling point
= Initial temperature = 35°C
= Heat of vaporization = 32.1 kJ/mol
From the Clausius-Claperyon equation

The normal boiling point of the substance is 389.78681 K
