Magma can push through holes or cracks in the crust of the volcano, causing a volcanic eruption. Which is when magma flows or erupts onto earth's surface, which is what you call lava (whenever it goes onto the earths surface).

Will the solubility of CaSO4 in 0.10 Molar CaF2 be smaller than, larger than, or the same as in pure water?

Kay [80]

Smaller than; less of it will dissolve before the solution is saturated

7. Jasmine wants to prevent getting burned by accidently touching a hot metal pipe, What would be the worst

tatyana61 [14]

Answer:

A) Glass

Explanation:

Glass is a conductor, so it allows heat to go through it (Ex. Touching a pie pan that came right out of the oven)

Rubber is an insulator, so heat has a hard time passing through (Ex. Using a rubber grip on a cast iron pan.

Cloth is also an insulator, so heat has a hard time passing through (Ex. Using a pot holder to prevent the counter from getting scarred)

Wood is also an insulator, so heat has a hard time passing through (Ex. Bedding for a rabbit hutch)

Hope this helps!!

A sample of argon has a volume of 1.2 L at STP. If the temperature is increased to 21 c and the pressure is lowered to 0.80 atm,

Nuetrik [128]

Answer:

The new volume is 1.62 L

Explanation:

Boyle's law says:

"The volume occupied by a given gas mass at constant temperature is inversely proportional to the pressure." It is expressed mathematically as:

Pressure * Volume = constant

o P * V = k

Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:

$\frac{V}{T}=k$

Gay-Lussac's law indicates that when there is a constant volume, as the temperature increases, the gas pressure increases. And when the temperature is decreased, the gas pressure decreases. So this law indicates that the quotient between pressure and temperature is constant.

Gay-Lussac's law can be expressed mathematically as follows:

$\frac{P}{T}=k$
