The latent heat of fusion refers to the solid to liquid or liquid to solid states.
Answer: Option C
<u>Explanation:
</u>
It is known that the inter conversion process from the states of solid to liquid is referred as fusion. So, for these conversions, the external energy in the heat form should be supplied to solid.
This external energy should be greater than the latent heat of solid in order to successfully break the bonds to form liquid. So the change in the enthalpy of the reaction while conversion from solids to liquids are termed as latent heats of fusion.
Even the inter-conversion from liquid to solid state will undergo change in enthalpy where the heat will be released and that is termed as latent heats of solidification. It is found that latent heat of solidification is equal in magnitude but opposite in direction with the latent heats of fusion.
Answer:
Pressure increases
Explanation:
"Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure."
Hi there!
p(a∩b) = 0.
Since a and b are mutually exclusive events, there is no overlap or intersection of events.
These two events CANNOT both occur, so the intersection of p(a) and p(b) does not exist.
Thus, p(a∩b) = 0.
Hello, I don't see a table, but I am guessing that you are referring to the one I attached (below).
Answer:
So, the correct order of events sorted chronologically is:
<u>
1. A nebula located in the Milky Way galaxy begins pulling nearby hydrogen atoms in its orbit.
</u>
2. The Nebula shrinks in its volume due to gravity, becoming denser and hotter. But, it's not hot enough for nuclear fusion.
<u>
3. The temperature in the core of the Nebula reaches 14 million Kelvin.
</u>
4. Hydrogen atoms begin shedding their electrons and colliding with one another.
5. The Sun enters the main sequence stage. The energy created as a result of its radiation begins nurturing life on planet such as Earth.
6. The Sun uses up all the hydrogen in its core.
<u>
7. The Sun expands greatly and cools. It is larger and redder.
</u>
8. The Sun completely runs out of hydrogen to fuse. Its outer layers are pushed away, and a cloud of ionized gas surrounds its core.
<u>
9. The Sun is a white dwarf with a dim glow.</u>
Hope this helps!
