Answer: What happens when the thermal energy of a substance increases is that D. Both the motion of the particles in the substance and the temperature of the substance increase.

Explanation: When thermal energy increases, it is due to particles moving faster. It also results in higher temperatures or heat.

24. A total of 165 J of work is done on a gaseous refrigerant as it undergoes compression. If the internal energy of the gas inc

Yuliya22 [10]

The total amount of energy transferred as heat is equal to 288 Joules.

<u>Given the following data:</u>

Internal energy = 123 Joules

Work done = 165 Joules

To calculate the total amount of energy transferred as heat, we would apply the first law of thermodynamics.

<h3>The first law of thermodynamics.</h3>

Mathematically, the first law of thermodynamics is given by the formula:

$\Delta E = Q - W$

<u>Where;</u>

$\Delta E$ is the change in internal energy.

Q is the quantity of heat transferred.

W is the work done.

Substituting the given parameters into the formula, we have;

$123 = Q - 165\\\\Q=123+165$

Q = 288 Joules.

A block slides to a stop as it goes 47 m across a level floor in a time of 6.35 s. a) What was the initial velocity? b) What is

UNO [17]

Answer :

(a) The initial velocity is, 14.8 m/s

(b) The acceleration is, $-2.33m/s^2$

Explanation :

By the 1st equation of motion,

$v=u+at$ ...........(1)

where,

v = final velocity = 0 s

u = initial velocity

t = time = 6.35 s

a = acceleration

The equation 1 will be:

$0=u+a(6.35}$

$u=-6.35a$ ..........(2)

By the 2nd equation of motion,

$s=ut+\frac{1}{2}at^2$ ...........(3)

where,

s = distance = 47 m

Now substitute equation 2 in 3, we get:

$47=(-6.35a)\times (6.35)+\frac{1}{2}\times a\times (6.35)^2$

By solving the term, we get:

$a=-2.33m/s^2$

The acceleration is, $-2.33m/s^2$

Now we have to calculate the initial velocity.

Using equation 2, we gte:

$u=-6.35a$

$u=-6.35s\times (-2.33m/s^2)$

$u=14.8m/s$

The initial velocity is, 14.8 m/s

1. Suppose you're working at a constant temperature , when you exert more pressure on an object

vova2212 [387]

Answer:

Decrease

Explanation:

Working at a constant temperature when more pressure is exerted, the volume decreases.

This is known as Boyle's law.

According to Boyle's law;

"the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".

Mathematically;

P₁V₁ = P₂V₂

P and V are pressure and volume

1 and 2 are initial and final states.
