How much heat is required to vaporize 1.5kg of liquid water at its boiling point

Physics
1 answer:
Dafna11 [192]3 years ago
3 0

Given:

Water, 1.5kg at boiling point

Required:

Heat required to vaporize at boiling point

Solution:

Water at boiling point is at 100degrees Celsius

Changing it into Kelvin, just dd 273 to 100 = 373 K

H = mCpT

H = (1.5kg)(4.184kJ/kg-K)(373K)

<span>H = 2340.9kJ</span>

Sidana [21]
Thank you for posting your question here at brainly. Below is the answer:

m = 80 kg
R = 6.4 x 10^6 m
Earth completes one rotation in 24 hours
Thus, T = 24 x 3600 s
Centripetral acceleration is given by 
ac = w^2R 
ac = (2 pie/T)^2R
ac = (2 pie/T)^2R = 4 pie^2/(24 x 3600)^2 x 6.4 x 10^6
ac = 0.034 m/s^2

Use your understanding of heat loss to ESTIMATE the cost of the lost energy through one standard window during an average summer
miskamm [114]

Answer:

The cost of energy is $ 0.34.

Explanation:

The energy is the capacity to do work.

The energy is a scalar quantity and its SI unit is Joule.

The commercial unit of energy is kWh.

Cost of 1 kWh energy = $ 0.17

energy loss by standard window is 2 kWh .

So, the cost of lost of energy is

Cost = $ 0.17 x 2 = $ 0.34

Which shows a decrease in fluid pressure? A. A fan is turned from high speed to low speed. B. Oxygen is compressed as it is put
Volgvan

Answer:

Option A.

A fan is turned from high speed to low speed.

Explanation:

It is important to note that air is also a fluid.

In a system, static pressure of air increases with the speed of rotation of the fan. This is because when the speed of the fan is increased, the force with which it is pushing the air molecules is increased. Since pressure is a relationship between force and area, the pressure of the air molecules will be increased.

Conversely, when the speed of the fan is reduced, the priming force on the air molecules will be reduced, hence the pressure of the air will drop.

This makes option A the correct option
