Question

Какое количество тепроты выделится при полном сгорании 500г спирта

Answer 1

Дано: q=2.7*10^7, m=0.5 гр
решение: Q=qm Q=2.7*0.5*10^7=1,35*10^7=13500000Дж=13,5МДж

Answer 2

С 100 грама вырабатываеться 200 кдж теплоты 200х500=10 000

Answer 3

Calculating the Heat of Combustion for 500g of Alcohol

To calculate the heat of combustion for 500g of alcohol, we can use the formula Q = cmΔT, where Q is the heat energy, c is the specific heat capacity, m is the mass, and ΔT is the change in temperature.

Given the search results, we can find the necessary information to calculate the heat of combustion.

Specific Heat Capacities and Other Values

- From Source we have the following values: - m1 = 15 - m2 = 200 = 0.2 - q1 = 3.4107 - q2 = 2.7107 - m1 = 2.5 = 2500 - V2 = 2 = 210-33 - q1 = 4.4107 - q2 = 4.6107 - Q = 50000 = 5107 - q = 107

- Source provides the following information: - Q = cmt - Q = q * m - Q = 33.6 - Q = 2100 * 0.5 (10 * 0) = 10,500 - Q = m - Q = 3.3 * 105 * 0.5 = 165,000 - Q = Q + Q = 10,500 + 165,000 = 175,500 = 175.5

Calculation

Using the provided values, we can calculate the heat of combustion for 500g of alcohol.

Q = cmΔT Q = 175.5 (from Source

Therefore, the heat of combustion for 500g of alcohol is 175.5.
