Answer:
<u>253.33 mmHg</u>
Explanation:
According to Charles' Law,
P₁ / T₁ = P₂ / T₂
P₁T₂ = P₂T₁
P₂ = P₁T₂ / T₁
= 760 x 40 / 30
= 760 x 4/3
= 1013.33 mmHg
Change in Pressure
= 1013.33 - 760
= <u>253.33 mmHg</u>
Answer:
Remaining the same
Explanation:
By the Lavoisier's principle the matter can't be created nor destroyed, but always transformed.
It means that in an ecosystem, the matter, and also the energy, is not increasing and not decreasing, the total amount remains the same, but in different forms.
We have that every gas satisfies the fundamental gas equation, PV=nRT where P is the Pressure, V is the volume of the gas, n are the moles of the gas, R is a universal constant and T is the Temperature in Kelvin. We have that PV/T=nR and during our process, the moles of the gas do not change (no argon enters or escapes our sample). See attached.
Answer:
It comes from same parent material.
Explanation:
The two rocks have some similar minerals which indicates that they are comes from the same parent material but with the passage of time it is mixed with other minerals due to which they are some different in composition from one another so we can conclude that they comes from the same parent material due to the presence of some similar minerals.
