The final volume of the balloon is 84.75 ml
<u><em>calculation</em></u>
The volume is calculated using Charles law formula
that is V1/T1= V2/T2 where,
V1= 5.00 x10^2 ml
T1= 22.0 °c into kelvin = 22 + 273 = 295 K
V2= ? ml
T2 =0.500 x 10^2 K
make V2 the subject of the formula by multiplying both side by T2
V2 is therefore = T2V1/T1
V2 = (0.500 x 10^2 K x 5.00 x10^2 ml) / 295 K = 84.75 ml
Answer:
Explanation:
The average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon-12.
Answer:
Velocity is vector quantity. So it needs <em>direction</em> in addoition to <em>speed</em>.
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion.
