<h3>
Answer:</h3>
272.43 K or -0.718°C
<h3>
Explanation:</h3>
We are given;
The initial pressure,P1 as 761 mmHg
Initial temperature, T1 as 0.00°C which is equivalent to 273.15 K
Final pressure as 759 mmHg
We are required to calculate the final temperature;
According to pressure law, the pressure of a gas and absolute temperature are directly proportional at constant volume.
That is; Pα T
Therefore, at varying pressure and temperature,
To get final temperature;
Therefore, the final temperature will be 272.43 K or -0.718°C
Answer:
7178.22 mL
Explanation:
Applying,
PV = P'V'................. Equation 1
Where P = Initial pressureof gas, V = Initial volume of gas, P' = Final pressure of gas, V' = Final volume of gas.
make V' the subject of the equation
V' = PV/P'.............. Equation 2
From the question,
Given: V = 2250 mL, P = 290 kPa, P' = 0.9 atm = (101×0.9) = 90.9 kPa
Substitute these values into equation 2
V' = (2250×290)/90.9
V' = 7178.22 mL
Answer:
Fractional Distillation could be used to:
- Obtain the different fractions of a crude which may have more uses and be more useful.
- Obtain ethanol from a mixture of ethanol and water.
Fractional Distillation is used to obtain one substance from a mixture. It depends on the boiling points of the substances.
Answer:
Looking at the positions of most if not all volcanoes, earthquakes, and major mountain belts, they are distributed mainly around the tectonic plate boundaries. ... The distribution of the volcanoes, earthquake epicenters, and major mountain belts are distributed in close proximity of the borders of the tectonic plates
