Because they believed that heavenly bodies’ circular motions where caused by their being attached to unseen resolving solid spheres
The pebbles become smooth and even because of erosion. the waves from the sea rub against the pebbles this is erosion. x
Answer:
THE NEW VOLUME AT 1 K IS 1.2 L
Explanation:
Using Charles' law which states that the volume of a given gas is directly proportional to its temperature provided the pressure remains constant.
Mathematically written as;
V1/T1 = V2/T2 at constant pressure
V1 = Initial volume = 6L
T1 = initial temperature = 5K
T2 = Final temperature = 1K
V2 = final volume = unknown
Re-arranging the equation by making V2 the subject of the equation, we obtain;
V2 = V1 T2 / T1
V2 = 6 * 1 / 5
V2 = 1.2 L
The new volume of the gas sample at 1 K is 1,2 L
Oxygen gains two electrons when it bonds to form a complete outer shell and magnesium loses two electrons when bonding to gain its full outer shell.
As electrons are negative, the oxygen (which gains electrons) will become negative and the magnesium (which loses electrons) will become positive.
The negative and positive ions will then attract to one another due to the magnetic pull of the positive and negative.
Im pretty sure it would also be 25
