The temperature T of a given mass of gas varies inversely with its volume V. The temperature of 90 cm^3 of a certain gas is 25°C. What will the temperature of the gas be when it is compressed to a volume of 20 cm^3? a. 112.5°C
b. 6°C
c. 54°C
d. 120°C

A. 112.5°C

Step-by-step explanation:

Use the inverse variation equation, y =

Replace y with T, and replace x with V:

T =

Plug in 90 as T and 25 as V, then solve for k:

T =

90 =

2250 = k

So, the equation is T =

Plug in 20 as V and solve for T:

T =

T =

T = 112.5

So, the temperature will be A. 112.5°C

the answer is f(x)=2x-1

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
