You have 16.6 g of water at 40.2 C. How many Joules are needed to warm the water to 44.8 C?

Q = 319.49 J

Explanation:

Given that,

Mass, m = 16.6 g

Initial temperature,

We need to find the heat needed to warm the water to 44.8 °C. The formula that is used to find the heat required is given by :

So, 319.49 J of heat is needed to warm water.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
