Calculate the volume of a liquid with a density of 5.45 g/mL and a mass of 65 g
avanturin [10]
The equation to calculate Density is Mass / Volume. You are given that the density is 5.45 and the mass is 65; 5.45 = 65 / v. So v = 65 / 5.45; v = 11.93 mL (or if you want your answer to consider significant figures, v = 12 mL).

Answer:

the importance of freezing in out daily lives

If you live in Canada you would know why the freezing and melting point of water is important. In the winter when it rises above freezing and rains then drops below freezing again, that water will freeze and cause the roads and sidewalks to be hazardous.

On a recent trip to the US I looked up the weather forecast and it was in Fahrenheit. I couldn't remember exactly what the freezing point of water was in Fahrenheit so I had to look it up. The forecast was for precipitation so I needed to know if it was likely to fall as rain, freezing rain (very dangerous) or snow.

When I use my windshield wipers I need to know that it's not pure water that's being squirted out. In the winter I need to know that there is anti-freeze in it so it won't freeze in the lines.

When I'm hiking up a mountain wearing a Camelback hydration system I need to know if the temperatures will drop below freezing or I will not have any water to drink as the water line will freeze. Same with uninsulated water bottles, and your sandwich.

Explanation:

the importance of evaporation and condensation

Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.

Evaporation is a very important part of the water cycle. Heat from the sun, or solar energy, powers the evaporation process. It soaks up moisture from soil in a garden, as well as the biggest oceans and lakes. The water level will decrease as it is exposed to the heat of the sun.

Although the level of a lake, pool, or glass of water will decrease due to evaporation, the escaped water molecules dont disappear. They stay in the atmosphere, affecting humidity, or the amount of moisture in the air.

Explain why need modifications about temperature and keep pressure atom
Yuri [45]

Answer:

The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. ... This means that they have more collisions with each other and the sides of the container and hence the pressure is increased.
