Answer:
Q = 5350.2 Joules.
Explanation:
<u>Given the following data;</u>
Mass, m = 26. 5g
Initial temperature, T1 = 0°C
Final temperature, T2 = 48.3°C
Specific heat capacity of water, c = 4.18 J/g°C.
*To find the quantity of heat*
Heat capacity is given by the formula;
Where;
- Q represents the heat capacity or quantity of heat.
- m represents the mass of an object.
- c represents the specific heat capacity of water.
- dt represents the change in temperature.
dt = T2 - T1
dt = 48.3 - 0
dt = 48.3°C
Substituting the values into the equation, we have;
Q = 5350.2 Joules.
Therefore, the amount of heat absorbed is 5350.2 Joules.
P O₂ = 736.2 torr
<h3>Further explanation</h3>
Given
P tot=760 torr
P H₂O = 23.8 torr
Required
P gas/O₂
Solution
Dalton's law of partial pressures stated that
<em>the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
</em>
Can be formulated:
P tot = P1 + P2 + P3 .... Pn
P tot = P H₂O + P O₂
760 torr = 23.8 torr + P O₂
P O₂ = 760 - 23.8
P O₂ = 736.2 torr
