Answer:
A.) 0.34 atm
Explanation:
Change the Celsius to Kelvin:
50.0 C = (273 + 50) = 323 K
22.0 C = ( 273 + 22) = 295 K
Gay-Lussac's Law: (P1/T1) = (P2/T2)
Rearranging that to solve for P2 gives
P2= (P1 x (T2/T1))
=0.370 atm x (295 K / 323 K)
= 0.338 atm
Answer A
Answer: What is one source of thermal energy in the interior of the Earth?
Explanation:
A balance in a lab measures the weight of a substance or object.
Weight is the mass of the body x the gravitation pull on the mass of the object.
So the mass of the object can be found by dividing the weight by gravitational constant.
The gravitational constant on earth is 1. so if a balance says that a substance weighs 300g then its mass is also 300g on earth because 300/1 = 300.
Hope that helps :)
In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of
fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
Hope this helped.
