Answer 1

Ответь Q=45C......

Вот вот вот вот вот

Answer 2

It seems like you're providing some values but the context is not clear. If I understand correctly, you're providing the following information:

• $2m = 50 \, \text{g}$
• $t_u = 25^\circ \text{C}$
• $t_2 = 75^\circ \text{C}$

And you're asking for the value of $Q$. However, the formula or relationship between these variables and $Q$ is not specified. In thermodynamics, the heat transfer ($Q$) can be calculated using the formula:

$Q = mc\Delta T$

Where:

• $Q$ is the heat transfer,
• $m$ is the mass of the substance,
• $c$ is the specific heat capacity of the substance,
• $\Delta T$ is the change in temperature.

If you provide the specific heat capacity ($c$) of the substance, I can help you calculate the heat transfer ($Q$).
