How many kPa are in 2,150 mmHg?<br> 2.83 kPa<br> 287 kPa<br> 1.61 ´ 104 kPa<br> 2.18 ´ 105 kPa
vlabodo [156]

Answer:

2150 mmHg ( 1 atm / 760 mmHg ) ( 101.325 kPa / 1 atm ) = 286.643 kPa

Therefore, the closest value from the choices is the second one which has the value of 287, this would be answer.

Which temperature change would cause a sample of an ideal gas to double in volume while pressure is held constant? A. From 400K
Advocard [28]

Answer:

The correct answer is option B. From 200K to 400K

Explanation:

Hello!

Let's solve this!

The ideal gas equation is the following PV = nRT

Where the variables are:

P: pressure

T: temperature

V: volume

R: universal constant of ideal gases

n: number of moles

We see in the equation the proportional relationship of volume with temperature.

We deduce that if the volume increases twice, then the temperature increases twice.

The temperature has to be in Kelvin, that's why we chose that answer.

Of the options, the correct answer is option B. From 200K to 400K
