Answer:
25116 J
Explanation:
Q = m × c × ΔT
c = 4.186 J/g°C
M=200 g
So,
Q = 200 × 4.186 × (40-10)
=200 × 4.186 × 30
=25116 J
Answer:
B: The shorter and more rounded the Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains
Explanation:
- The Appalachian mountains form a system of mountains in eastern North America and are older than rocky mountains as they were formed 480 million years ago and are similar to those of the alps. They form a barrier to the east to the west.
- They extend to southeast Canada and form zones of 300 miles wide. They form the mountain ranges surrounding hills and the dissected plateaus forming at an elevation of 6,684 meters from the sea level. <u>Whereas the rocky mountains are younger and have an elevation of 4,401 meters.</u>
The volume of the gas expansion is 0.71 liters.

Boyle's law</h3>
Boyle's law states that the volume of a given mass of a gas is inversely proportional to its pressure provided that temperature remains constant.
P₁V₁ = P₂V₂
where;
- P₁ = 30 psi
- V₁ = 0.35 liters
- P₂ = 1 atm = 14.7 psi
The volume of the gas expansion is calculated as follows;
