In simple diffusion, small molecules without charges such as oxygen and carbon dioxide flow through a plasma membrane without assistance and without expending energy. Other substances such as proteins<span>, glucose and charged particles called ions cannot pass through the selectively permeable membrane.</span>

Explanation:
Hello!
In this case, since we have hot and cold water, we infer that as hot water cools down, cool water heats up based on the first law of thermodynamics; thus, we can write:
In such a way, we can write the expression in terms of mass, specific heat and temperature change:
However, since they both have the same specific heat and the same mL are in g due to the 1.00-g/mL density, we obtain:
Now, we plug in to obtain:
Best regards!
