Answer:
Amount of heat absorbed by water is 2604.54 J.
Explanation:
Amount of heat absorbed by water = 
where m represents mass, C represents specific heat and 
represents change in temperature.
Here 
g , 
and = (final temperature - initial temperature) = (29.5-21.2) 
= 8.3
So, amount of heat heat absorbed by water
= 
= 2604.54 J
Answer:
In many plants species , a plant have different patterns on their leaves. It is because of mutations which occurs due to change in the DNA or genetic makeup because of environmental factors such as UV light and other substances.
Explanation:
Mutation refers to the sudden change which occurs in the genetic makeup of the cell due to the exposure to harmful radiations such as UV radiation and gamma radiation. In Plant cells, mutation also occurs due to the external environment. Sometimes it occurs naturally and sometimes due to certain radiation or smoke.

Answer:
Acetic acid is often called “glacial acetic acid”. The origin of this name can be attributed to acetic acid's high freezing point. Acetic acid freezes into a solid at a temperature very close to room temperature: 16.5 ºC, or 62 ºF. When it freezes, it kind of looks like ice; because of the word “glacial”.
Explanation:
A) amount of matter it contains.
