The pressure of a gas p(v) varies inversely with the volume of gas v. the pressure of a gas measures 8kg/cm^2 when its volume is
40cm^3.
which equation can be used to find the pressure of the gas when its volume is changed.
A. p(v)=320v
B. p(v)=320 over v
C. p(v)=5v
D. p(v)=5 over v
2 answers:
Answer:
B.
Step-by-step explanation:
We are given that
The pressure of gas p(v) varies inversely with the volume of gas v.
Pressure of gas measures=
Volume of gas=
We have to find the equation that can be used to find the pressure of the gas when its volume is changed.
According to question
p(v)
Where k=proportionality constant
Substitute the given values then, we get
Substitute the value of k then, we get
Hence,option B is true.
Answer:
B
Step-by-step explanation:
Since p and v vary inversely then the equation relating them is
p = ← k is the constant of variation
to find k use the condition p = 8 when v = 40
k = pv = 8 × 40 = 320
⇒ p(v) = → B

Answer:
G n − 29 < 53
Step-by-step explanation:
If n = 81 ;
Put n = 81 into each and see if it holds true:
F 3n < 84
3(81) < 84
243 < 84 - - - - untrue
G n − 29 < 53
81 - 29 < 53
52 < 53 - - - - - True
H 2n < 162
2(81) < 162
162 < 162 - - - - untrue
J n + 5 < 76
81 + 5 < 76
86 < 76 - - - - - untrue
Only true statement :
G n − 29 < 53
