400.0 ml of a gas are under pressure of 80.0 kpa what would the volume of the gas be at a pressure of 100.0 kpa

Ber [7]

Answer:

The final volume is 320 mL at pressure of 100 kPa.

Step-by-step explanation:

Boyle's law gives the relation between volume and pressure of a gas. It states that at constant temperature, volume is inversely proportional to its pressure such that,

$V\propto \dfrac{1}{P}\\\\P_1V_1=P_2V_2$

Let

$V_1=40\ mL\\\\P_1=80\ kPa\\\\P_2=100\ kPa$

We need to find $V_2$ . Using above equation, we get :

$V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{400\times 80\times 10^3}{100\times 10^3}\\\\V_2=320\ mL$

So, the final volume is 320 mL at pressure of 100 kPa.

1. Andrew ran a marathon in about 1.56 x 10^4 s. (a) Write Andrews time in standard notation. (b) Evelyn ran a marathon in 4 h a

romanna [79]

Answer:

(a) 15,600 s
(b) Evelyn

Step-by-step explanation:

(a) 1.56×10^4 = 1.56×10000 = 15,600

(b) There are 3600 seconds in an hour, so Andrew's time was

15600 s/(3600 s/h) = 13/3 h = 4 1/3 h

1/3 hour is 20 minutes, so Evelyn's time of 4:16 is shorter than Andrew's time of 4:20.

Two dice are rolled, and the sum of the face values is six. What is the probability that at least one of the dice came up a thre

gizmo_the_mogwai [7]

Answer : $P(\text{ atleast one of the dice come up 3})= \frac{1}{5}$

Explanation :

We know that ,

Sample space of " sum of faces is 6"= $\{(3,3),(4,2),(2,4),(5,1),(1,5)\}$

Atleast one of the dice come up 3 = $\{(3,3)\}$

So,

$Probability = \frac{\text{No. of favourable outcomes}}{\text{Total no. of outcomes}}$

$P(\text{ atleast one of the dice come up 3})= \frac{1}{5}$
