Question

В алюминиевой калориметр , содержащий 0.62 кг воды при 300 К, ввели 0,1 кг водяного пара при 100 С. Чему равна масса калориметра, если температура смеси стала 37 С

Answer 1

300К=27С

$c_am_a(t-t_1)+c_vm_v(t-t_1)=Lm_p+c_vm_p(t_2-t)$

$920m_a(37-27)+4200*0.62(37-27)=2300000*0.1+4200*0.1(100-37)$

$9200m_a+26040=230000+26460$

$920m_a=23042$

$m_a\approx25(kg)$

Ответ: 25 кг

Answer 2

Calculation of the Mass of the Calorimeter

To calculate the mass of the calorimeter, we need to use the principle of conservation of energy. The total energy before and after the mixing of water and steam should be equal.

Given: - Mass of water in the calorimeter = 0.62 kg - Initial temperature of the water = 300 K - Mass of steam added = 0.1 kg - Temperature of the steam = 100 °C - Final temperature of the mixture = 37 °C

To solve this problem, we can use the equation:

m1 * c1 * (T1 - T) + m2 * c2 * (T2 - T) = 0

Where: - m1 = mass of water - c1 = specific heat capacity of water - T1 = initial temperature of water - T = final temperature of the mixture - m2 = mass of steam - c2 = specific heat capacity of steam - T2 = temperature of steam

First, let's convert the temperature of the steam from Celsius to Kelvin:

T2 = 100 + 273.15 = 373.15 K

Next, we need to find the specific heat capacities of water and steam. The specific heat capacity of water is approximately 4.18 kJ/kg·K, and the specific heat capacity of steam is approximately 2.03 kJ/kg·K.

Now we can substitute the values into the equation and solve for the mass of the calorimeter:

0.62 * 4.18 * (300 - 37) + 0.1 * 2.03 * (373.15 - 37) = 0

Simplifying the equation:

0.62 * 4.18 * 263 + 0.1 * 2.03 * 336.15 = 0

0.62 * 4.18 * 263 = -0.1 * 2.03 * 336.15
