Question

1)какое количество теплоты выделится при охлаждении 50г серебра на 4 градуса цельсии?

Answer 1

Q=cm *дельта t Q= 0,5 *4*234=468Дж

Answer 2

Calculation of Heat Released

To calculate the amount of heat released during the cooling of 50 grams of silver by 4 degrees Celsius, we can use the formula:

Q = m * c * ΔT

Where: - Q is the amount of heat released - m is the mass of the substance (in this case, silver) - c is the specific heat capacity of the substance - ΔT is the change in temperature

In this case, the mass of silver is 50 grams and the change in temperature is 4 degrees Celsius.

Now, we need to find the specific heat capacity of silver. According to the search results, I couldn't find the specific heat capacity of silver in the snippets provided. However, the specific heat capacity of silver is approximately 0.235 J/g°C.

Using this value, we can calculate the amount of heat released:

Q = m * c * ΔT

Q = 50 g * 0.235 J/g°C * 4°C

Calculating this equation gives us:

Q = 47 J

Therefore, approximately 47 Joules of heat will be released during the cooling of 50 grams of silver by 4 degrees Celsius.

Please note that the specific heat capacity of silver may vary slightly depending on the source, but the value used here is a commonly accepted approximation.
