Answer:
1÷60 h
time equals distance upon speed
Answer:
Nitrogen, Oxygen, Argon.
Explanation:
The three (3) most abundant gases in the dry atmosphere are"
- Nitrogen
- Oxygen
- Argon
These are not the only components of dry air. Dry atmosphere is made up of:
- 78.09% Nitrogen;
- 20.95% Oxygen;
- 0.93% Argon;
- 0.04% Carbon dioxide;
- Other gases
Conservation law, also called law of conservation, in physics, several principles that state that certain physical properties (i.e., measurable quantities) do not change in the course of time within an isolated physical system
In the freezing physical change, when 210.0 g of water a 0 degrees freezes into ice, it gives off 71.0 kJ of heat.
<h3>What is freezing?</h3>
It is a physical change in which liquids give off heat to form solids.
We have 210.0 g of water at 0°C. We can calculate the amount of heat given off when it freezes into ice using the following expression.
Q = ΔH°fus × m
Q = 0.334 kJ/g × 210.0 g = 70.1 kJ
where,
- Q is the heat released.
- ΔH°fus is the latent heat of fusion.
- m is the mass.
In the freezing physical change, when 210.0 g of water a 0 degrees freezes into ice, it gives off 71.0 kJ of heat.
