Answer:
A dilute aqueous potassium nitrate solution is a homegeneous mixture.
Explanation:
Kinetic energy is an object in motion, potential energy is the potential for energy. Energy is the ability to make change, so kinetic energy is in the process of impacting something else.
To solve this we assume
that the gas inside the balloon is an ideal gas. Then, we can use the ideal gas
equation which is expressed as PV = nRT. At a constant pressure and number of
moles of the gas the ratio T/V is equal to some constant. At another set of
condition of temperature, the constant is still the same. Calculations are as
follows:
T1 / V1 = T2 / V2
T2 = T1 x V2 / V1
T2 = 25 x 3 / 2
<span>T2 = 37.5 degrees Celsius</span>
