Answer:
The volume will goes to decrease.
Explanation:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
when pressure is going to increase the volume will goes to decrease and vice versa.
Consider the initial volume is 10 L at initial pressure of 15 atm when pressure is increased to 30 atm the volume will be,
Now we will put the values in formula,
P₁V₁ = P₂V₂
15 atm × 10 L = 30 atm × V₂
V₂ = 150 atm. L/ 30 atm
V₂ = 5 L
Answer: 
Explanation:
Given
Mass of water in the sample is 
Temperature changes from
to 
Change in temperature is 
We know, specific heat of water is 
Heat absorbed is given by

Thus, water absorbs
of heat from hot plate.
There are three rock types in the rock cycle including: igneous, sedimentary, and metamorphic rock.
<u>Explanation:</u>
Any solid or combination of minerals which naturally occurs is understood as a rock. It is classified by the contained minerals, its chemical composition and the manner it is made.
<u>Igneous Rocks:</u> It is generated by magma or lava being refrigerated and solidified. The magma may be produced from partial melting of established rocks, either in the mantle or crust of a planet. The melting is usually caused by one or more of three methods: temperature rise, pressure decrease, or composition transition.
<u>Sedimentary Rocks:</u> These forms that are developed by aggregation or deposition of tiny particles and eventual cementation of mineral or organic substances on the surface of the Earth's ocean floor or other water bodies. Sedimentation is the general term for mechanisms that cause settlement of such particles.
<u>Metamorphic Rocks:</u> These occur from the alteration of different rock types in a technique called metamorphism, which implies change of shape. The initial rock or protolith is heated where temperatures between 150 to 200 ° C and a pressure level of 100 megapascals (1,000 bar) or more induces significant physical or chemical changes.
