WINSTONCH [101]3 years ago

Answer:

If gas is cooled the particles will then stop moving about really fast and start to form a liquid. This is called condensation.. (i think) and it happens at the same amount of temperature as or when boiling. Evaporation is dependent on individual particles gaining enough energy to escape the surface of the liquid and become gas particles.

Another comment: Can you please look at my question? I really need help as well.

Water could be made to boil lower than its normal boiling point of 100 degrees Celsius at 92 degrees Celsius by?
KonstantinChe [14]
Water could be made to boil lower than its normal boiling point of 100 degrees Celsius at 92 degrees Celsius by lowering the atmosphere or external  pressure.

The boiling point is the temperature at which the vapor pressure of liquid equals the external or atmosphere pressure.

So, if you decrease the external pressure the temperature needed for the liquid reach the lower external pressure is also lower..


You can accomplish by taking the water to higher levels in the Earth (atmosphere pressure at high altitudes is lower than at sea level) or by creating vaccum.

A rectangular block of copper metal weighs 1896 g. The dimensions of the block are 8.4 cm by 5.5 cm by 4.6 cm. From this data, w
Fed [463]

Answer:

Density = 8.92 g/cm³

Explanation:

Density shows the relation of the mass and volume of a determined object. We have this deffinition:

Density = mass / volume

First of all, we calcualte the volume of the block of copper metal, with the data given:

8.4 cm . 5.5 cm . 4.6 cm = 212.52 cm³

Now we replace at the density formula:

Density = 1896 g /212.52 cm³  = 8.92 g/cm³
