Answer:
The amount of heat released is 11.3 KJ
Explanation:
H20(g) -> H20(l) + heat
This reaction is changing state from gaseous to liquid without changing the temperature. This heat is know as Latent heat. It is the energy required for a phase change.
Heat released by 5 g of water vapor (Q) = M × L
where M = mass of vapor
L= latent heat
Latent heat can be divide into 2
- Latent heat of fusion
- Latent heat of vaporization
Since we are change the gaseous state to liquid, we will be working with Latent heat of vaporization which has a value of 22.6 x 10 ∧5 J/kg
(Q) = M × L
= 0.005 x 22.6 x 10 ∧5
= 11300 J
= 11.3 KJ
Answer:
<h2>mass = 1102.50 g</h2>
Explanation:
The density of a substance can be found by using the formula
Making mass the subject we have
<h3>mass = Density × volume</h3>
From the question
Density of silver = 10.50 g/cm³
Volume = 105 cm³
Substitute the values into the above formula and solve for the mass
That's
mass = 10.5 × 105
We have the final answer as
mass = 1102.50 g

Answer:
Sleep homeostasis denotes a basic principle of sleep regulation. A sleep deficit elicits a compensatory increase in the intensity and duration of sleep, while excessive sleep reduces sleep propensity

Answer:
Matter
Explanation:
Solids, liquids, and gases are the three types of matter that can be found in the world around us today. In solids, all of the particles are close together. They move more in liquids, but they are spread out in gas.
