The change in the temperature of the pan of water on the Kelvin and Fahrenheit scales is 328.15K and 131°F respectively.

<h3>Temperature Scale</h3>

Temperature scale is simply the methodology of calibrating the physical quantity of temperature.

There are 3 main temperature scales, namely; Celsius, Fahrenheit, and Kelvin.

The expression for conversion are;

  • Celecius to Kelvin : 0°C + 273.15 = 273.15K
  • Celecius to Fahrenheit : (0°C × 9/5) + 32 = 32°F

Given the data in the question;

  • Initial temperature of pan I = 23°C
  • Final temperature of pan F = 78°C

First we determine the change in temperature.

ΔT = Final temperature - Initial temperature

ΔT = 78°C - 23°C

ΔT = 55°C

The change in temperature on the Kelvin scale

ΔT = 55°C = 55°C + 273.15 = 328.15K

The change in temperature on the Fahrenheit scale

ΔT = 55°C = (55°C × 9/5) + 32 = 131°F

Therefore, the change in the temperature of the pan of water on the Kelvin and Fahrenheit scales is 328.15K and 131°F respectively.

the change in the temperature of the pan of water on the Kelvin and Fahrenheit scales is 328.15K and 131°F respectively.

A technician is checking refrigerant system pressures. Both high- and low-side service ports are located on the A/C compressor.
konstantin123 [22]

Answer:

Two major causes are outline bellow

1. The presence of air in the system

2. Clogged condenser

Explanation:

1. The presence of air in the system

One of the causes that have been established in relation to high compressor discharge pressure is the presence of air in the system. When this takes place, your best solution is to recharge the system.

2. Clogged condenser

Another is a clogged condenser in which case you will need to clean the condenser so that it will function properly. When you happen to spot that the discharge valve is closed and it is causing high discharge pressure on the compressor, you can solve that easily by opening the valve

How many atoms are there in 3.4moles if helium ,show the calculation
prohojiy [21]
Answer: 20.4752789138x x  10^23 atoms
To count how many atoms in moles you need to know Avogadro's number. Avogadro's number dictate that for every mole there is 6.022140857 × 10^23 molecule/atoms.
Then 3.4 moles of helium will be 3.4x 6.022140857 x  10^23 atoms= 20.4752789138x x  10^23 atoms

Which describes a positive or negative net force acting on an obiect? Check all that apply.
Murrr4er [49]

Answer:

It can cause an object to accelerate.

It can cause an object to stop moving.

It can cause an object to start moving.

It can cause an object to change directions.

Explanation:

When the velocity of an object is increased in the same direction, the object is said to have positive acceleration. If it increases its velocity in a direction that is opposite to the original direction, it is negative acceleration.

When an object that's already moving is made to stop, it is said to have decelerated. Deceleration is negative acceleration.

When an object at rest is made to move by applying a force, it is said to have accelerated to some final velocity, during its motion for some duration.

An object at rest will remain at rest is said to have no net force acting on it.

Tubby and his twin brother Libby have a combined mass of 200 kg and are zooming along in a 100 kg amusement park bumper car at 1
harkovskaia [24]

Answer: 14.1 m/s

Explanation:

We can solve this with the Conservation of Linear Momentum principle, which states the initial momentum p_{i} (before the elastic collision) must be equal to the final momentum p_{f} (after the elastic collision):

p_{i}=p_{f} (1)

Being:

p_{i}=m_{1}V_{i} + m_{2}U_{i}

p_{f}=m_{1}V_{f} + m_{2}U_{f}

Where:

m_{1}=200 kg +100 kg=300 kg is the combined mass of Tubby and Libby with the car

V_{i}=10 m/s is the velocity of Tubby and Libby with the car before the collision

m_{2}=25 kg + 100 kg=125 kg is the combined mass of Flubby with its car

U_{i}=0 m/s is the velocity of Flubby with the car before the collision

V_{f}=4.12 m/s is the velocity of Tubby and Libby with the car after the collision

U_{f} is the velocity of Flubby with the car after the collision

So, we have the following:

m_{1}V_{i} + m_{2}U_{i}=m_{1}V_{f} + m_{2}U_{f} (2)

Finding U_{f}:

U_{f}=\frac{m_{1}(V_{i}-V_{f})}{m_{2}} (3)

U_{f}=\frac{300 kg(10 m/s-4.12 m/s)}{125 kg} (4)

Finally:

U_{f}=14.1 m/s
