Answer:
NaCl is ionic so has strong ionic bonds between ions; paraffin is molecular and has weak intermolecular forces between molecules
Explanation:
KE = 1/2*m*v^2
KE = 1/2*150kg*(15 m/s)^2
KE = 75kg * 225m²/s²
KE = 16875 kg*m²/s²
KE = 16875 N*m
KE = 16,875 J
According to Charle's law
The volume of an ideal gas is directly proportional to the temperature, keeping pressure and moles constant
Thus if we increase temperature of a gas it will increase its volume
In case of balloon, the gas will expand on heating and contract on cooling
Thus our hypothesis supported is
Gases expand when heated and contract when cooled
14 uranium atoms in pure uranium
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
