Answer:
Explanation:
Hello,
In this case, we find the following states:
a. Liquid salt water at 28.0 °C.
b. Liquid salt water at 102.5 °C.
c. Vapor salt water at 102.5 °C.
The first process (1) is to heat the liquid water from 28.0 °C to 102.5 °C and the second one (2) to vaporize the liquid salt water. In such a way, each process has an amount of energy that when added, yields the total energy for the process as shown below:
Best regards.
Answer:
New volume = 150 mL
Explanation:
Initial temperature, T₁ = 35°C
Initial volume, V₁ = 350 mL
We need to find the change in volume when the temperature drops to 15°C.
The relation between the temperature and the volume is given by Charle's law. Let new volume is V₂. It can be given by :
So, the new volume is 150 mL.
Answer: During winter the Northern Hemisphere leans away from the sun, there are fewer daylight hours and the sun hits us at an angle. This makes it appear lower in the sky. In equatorial regions the length of days and the directness of sunlight don't change as much.
Hope this helps :)
