Seventh grade > G.8 Predict forces using Newton's third law G9S Isaac Newton was born in the 1600s and studied how objects move. He discovered three
fundamental laws about forces and motion. According to Newton's third law, for every force,
there is an equal and opposite force.
Consider the following force:
A bar magnet is pushing on a disc magnet.
According to Newton's third law, what other force must be happening?
The disc magnet is pushing on the bar magnet.
The disc magnet is pulling on the bar magnet.

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
