How much heat is removed from 60 grams of steam at 100 °C to change it to 60 grams

Physics
1 answer:
Harrizon [31]2 years ago
4 0

Answer:

45200J

Explanation:

Given parameters:

Heat of vaporization of water  = 2260J/g

Mass of steam = 20g

Temperature = 100°C

Unknown:

Energy released during the condensation  = ?

Solution:

This change is a phase change and there is no change in temperature

To find the amount of heat released;

         H  = mL

m is the mass

L is the latent heat of vaporization

Insert the parameters and solve;

         H  = 20g x 2260J/g

          H = 45200J

Human blood has a density of approximately 1.05×10'3 kg/m'3 .Use this to estimate the difference in blood pressure between the b
Murljashka [212]

Answer:

formula

ΔP= PgΔh

Explanation:

Calculation.

ΔP = (1.05 x 10^3kg/m^3)(9.8m/s^2)(6ft equivalent to 1.8288m)

ΔP = 1.05 x 10^3 kg/m^3 x 9.8m/s^2.

x1.8288.

ΔP = 1.88 x 10^4 Pa.

How does volcanic ash in earth's atmosphere affect solar radiation?
Irina-Kira [14]

The answer is it increases the amount of solar radiation that is redirected into space. Most of the particles emitted from volcanoes cool the earth by covering entering solar radiation. The cooling result can last for months to years contingent on the features of the eruption.

What happens if two black holes collide
blagie [28]

When two black holes spiral around each other and ultimately collide, they send out gravitational waves - ripples in space and time that can be detected with extremely sensitive instruments on Earth. ... If confirmed, it would be the first known light flare from a pair of colliding black holes.
