Answer:

<h3>The answer is 40 km/ hr</h3>

Explanation:

To find the speed we use the formula

speed \:  =  \frac{distance}{time}

From the question

The distance is 400 km

The time is 10 hours

Substitute the values into the above formula

That's

Speed  =  \frac{400 \: km}{10 \: hours}

We have the final answer as

<h3>40 km/ hr</h3>

Hope this helps you

A sample of a monatomic ideal gas initially at temperature T, undergoes a process during which the pressure of the gas triples a
Allisa [31]

Answer:

B) 8 T.

Explanation:

For an ideal gas , the gas law that it follow is as follows

P₁V₁ / T₁ = P₂ V₂ /T₂

This law is followed by all the gases whether mono atomic or diatomic.

In this case following information are given

P₂ / P₁ = 3

V₂ / V₁ = 3

T₁ = T

T₂ = ?

From the gas law formula given , we have

T_2 =\frac{P_2\times V_2\times T_1}{P_1\times V_1}

V_2 = \frac{P_2}{P_1} \times\frac{V_2}{V_1}\times T

= 3 X 3 T

= 9 T

Change in temperature = 9T - T = 8 T.
