How much energy ( in joules ) is released when 0.06 kilograms of mercury is condensed to a liquid at the same temperature ? A. 697.08 J
B. 17,705.1 J
C. 20,075.04 J
D. 51,302.88 J

Please include how you got your answer , thank you.

Answers

Answer 1
Answer:

Answer:

B. 17,705.1 J

Explanation:

The hear released when the mercury condenses into a liquid is given by:

Q=m \lambda_v

where

m = 0.06 kg is the mass of the mercury

\lambda_v is the latent heat of vaporization

For mercury, the latent heat of vaporization is \lambda_v = 296 kJ/kg, so the heat released during the process is:

Q=(0.06 kg)(296 kJ/kg)=17.76 kJ = 17,760 J

So, the closest option is

B. 17,705.1 J

Answer 2
Answer:

The energy ( in joules ) released when 0.06 kilograms ofmercury is condensed to a liquid at the same temperature is about 697.08 J. inother to solve this problem, should know the latent heat of fusion of mercurywhich is equal to about 11.4 kJ/kg and multiplying by mass of mercury.

Which is occurring when work is being done? energy is being reverted. energy is being decreased. energy is being increased. energy is being transferred.?

Answers

The work is an effect that is observed due to the application of force. Taking the concern of work-energy principle, the work is done when there is a transfer of energy take place.

What is Work Done?

When some magnitude of the force is being applied on an object to displace, then the term used to describe the effect is known as work done.

The mathematical expression for the work done is given as,

W = F × d

here,

F is the magnitude of applied force.

d is the displacement.

If we compare work with energy then, Energy, on the other hand, is the ability to do work. According to the work-energy principle, a change in the kinetic energy is equivalent to the net work done by the object. Therefore, energy is being transferred from one point to another when work is being done.

Thus, we can conclude that the work is done when a transfer of energy takes place.

Answer;

Energy is being transferred

Explanation;

  • Work is the force applied over a given distance, in other words work is the product of force and distance.

Work = force × distance.

  • Work is measured in Joules.
  • Energy on the other hand, is the ability to do work.
  • According to the principle of work-energy a change in the kinetic energy is equivalent to the net work don e by the object. Therefore, when work is being done energy is being transferred from one point to another.

Answers

The answer is current.

Current in the context of an electrical circuit is the flow of charge. Current is a quantity that is physical and can be measured. Current is defined as the rate of the flow charge past a certain point in a circuit. Current is expressed in Amperes which is equal to 1 coulomb/1second.
