Answer:
The amount of heat required to raise the temperature of a 32g sample of water from 8°C to 22°C is 1,874.432 J
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).
Between heat and temperature there is a direct proportional relationship. The constant of proportionality depends on the substance that constitutes the body and its mass, and is the product of the specific heat and the mass of the body. So, the equation that allows to calculate heat exchanges is:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT is the variation in temperature.
In this case:
- c= 4.184

- m= 32 g
- ΔT= Tfinal - Tinitial= 22°C - 8°C= 14°C
Replacing:
Q= 32 g* 4.184
*14 °C
Solving:
Q= 1,874.432 J
<u><em>The amount of heat required to raise the temperature of a 32g sample of water from 8°C to 22°C is 1,874.432 J</em></u>
Answer:
1. 10.37114 psi
2. 71.5178 KPa
3. 71517.8 Pa
4. 536.56 mmHg.
5. 21.12352 inHg
Explanation:
From the question given,
Pressure = 0.706 atm
The pressure in other units of measurement is obtained as follow:
1. Pressure in Psi
1 atm = 14.69 psi
Therefore, 0.706 atm = 0.706 x 14.69 = 10.37 psi
2. Pressure in KPa
1 atm = 101.3 kPa
Therefore, 0.706 atm = 0.706 x 101.3 = 71.5178 KPa
3. Pressure in Pa
1 atm = 1.013x10^5 Pa
Therefore, 0.706 atm = 0.706 x 1.013x10^5 = 71517.8 Pa
4. Pressure in mmHg
1 atm = 760mmHg
Therefore, 0.706 atm = 0.706 x 760 = 536.56 mmHg
5. Pressure in inHg
1 atm = 29.92 inHg
Therefore, 0.706 atm = 0.706 x 29.92 = 21.12352 inHg
