The pressure of a gas (relative to vacuum) inside a rigid container at 0 °C is:
gizmo_the_mogwai [7]

The pressure of a gas inside a rigid container at 0 °C will not be zero, but will somewhat be less than it would be at 25 °C.

<h3>Temperature and pressure of gases</h3>

According to Charle's law of gases, the pressure of a gas is directly proportional to its temperature. This is based on the condition that the volume of the gas does not change.

Thus, for a gas inside a rigid container, the pressure at 0 °C may not be zero. However, the pressure will be less than it would be if the temperature were to be 25 °C.

Car A is traveling north on a straight highway and car B is traveling west on a different straight highway. Each car is approach
guapka [62]

Answer:

129 km/hr

Explanation:

Distance of Car A North of the Intersection, y=0.3km

Distance of Car B West of the Intersection, x=0.4 km

The distance z,  between A and B is determined by the Pythagoras theorem

z^2=x^2+y^2

z^2=0.4^2+0.3^2=0.25\\z=\sqrt{0.25}=0.5km

Taking derivative of z^2=x^2+y^2

2z\frac{dz}{dt}= 2x\frac{dx}{dt}+2y\frac{dy}{dt}

\frac{dx}{dt}=90km/hr, \frac{dy}{dt}=95km/hr

2(0.5)\frac{dz}{dt}= 2(0.4)X90+2X0.3X95\\\frac{dz}{dt}=72+57=129

The distance z, between the cars is changing at a rate of 129 km/hr.
