Answer:
Cold water
Explanation:
A simple way to solve this kind of problems is to keep in mind that:
<em>Solids have stronger intermolecular attractive forces than liquids, and liquids have stronger forces than gases.</em>
Cold water behaves more similarly to solids than hot water. Conversely, hot water behaves more similarly to gases than cold water. Thus, cold water has stronger intermolecular attractive forces than hot water.
The amount of energy absorbed by the 325g of water is 57,057J. Details about calorimetry can be found below.
<h3>How to calculate energy?</h3>
The energy absorbed by a mass of substance can be calculated using the following formula;
Q = mc∆T
Where;
- Q = quantity of heat absorbed
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
Q = 325g × 4.18 × (92 - 50)
Q = 57,057J
Therefore, the amount of energy absorbed by the 325g of water is 57,057J.

Answer:- 
.
Solution:- Aspartame is a artificial sweetener with molecular formula 
and it's molecular mass is 294.3 gram per mol.
We have been given with 4.50 mg of aspartame and asked to calculate the moles. For mass to moles conversion we divide the given mass in grams by molar mass.
Since, the mass is given in mg, we need to convert it to g first.
1 mg = 0.001 g
So, 
= 0.00450 g
Now let's calculate the moles on dividing the grams by molar mass as:
=
Hence, are present in 4.50 mg of aspartame.
