Answer:
Approximately 56.8 liters.
Assumption: this gas is an ideal gas, and this change in temperature is an isobaric process.
Explanation:
Assume that the gas here acts like an ideal gas. Assume that this process is isobaric (in other words, pressure on the gas stays the same.) By Charles's Law, the volume of an ideal gas is proportional to its absolute temperature when its pressure is constant. In other words
,
where
is the final volume,
is the initial volume,
is the final temperature in degrees Kelvins.
is the initial temperature in degrees Kelvins.
Convert the temperatures to degrees Kelvins:
.
.
Apply Charles's Law to find the new volume of this gas:
.
We can use a ratio to solve this question. Lets refer to the amount formed by the formula as a serving
1 serving needs 3/8 gal
We want to create 7/9 servings extra, so
1 + 7/9 = 16/7
1 : 3/8
16/7 : x
1/(3/8) = (16/7) / x
8 / 3 = 16x / 7
x = 7/6
He needs to use 7/6 gallons of water.
Answer:
I'm assuming atmospheric pressure, since it says she is measuring pressure exerted my atmospheric gases
Answer:
6
Explanation:
This question is seeking for an equivalent of one expression. The first expression says 1/3 of 12, which means 1/3 × 12 = 4. To find 2/3 of a number that will give us 4, we say
Since; 1/3 of 12 is 4
Then, 4 = 2/3 of x, where x is the number, which when multiplied by two-third (2/3) will result to 4.
4 = 2/3 × x
4 = 2x/3
Cross multiply
2x = 3 × 4
2x = 12
x = 12/2
x = 6.
This means that; 1/3 of 12 = 2/3 of 6
