What would happen to the pressure if the volume were reduced to 0.5 l and the temperature increased to 260 ∘c?

1 answer:

8 0

<span>The ideal gas law. PV=nRT pressure x volume = moles x Faraday's constant x Temp Kelvin (C+273) Original data Pressure 1 atmosphere Volume 1 liter Temp 25C = 298K New data Volume 0.5 liter pressure X Temp 260C = 533K P1v1T1 = P2v2T2 plug and chug. (1)(1)(293) = (x)(0.5)(533) Solve for X, which is the new pressure. </span>

A scientist is trying to determine whether a certain substance is radioactive. Which question would be most helpful to ask?

Well a question to ask would be if the mass of the material has changed significantly as that would determine that the substance is radioactive or if there have been any high readings found by a Geiger meter in certain period of time

hope that helps

3. Two people are playing tug of war. One person pulls to the right with 32 N of force. The other person pulls to the left with

SVETLANKA909090 [29]

The net force = -5 N

The direction : to the left(negative sign)

<h3>Further explanation </h3>

Net force : the sum of all forces acting on an object

Force is a vector quantity that has both magnitude and direction,

We agree that the move up and to the right is a positive sign, while down and to the left is a negative sign.

The direction of the force (horizontal motion) is to the right (+32 N), and to the left (-37 N), so the net force :

$\tt \sum F=F~right-F~left\\\\\sum F=32-37\\\\\sum F=-5~N$
