The new volume of the hot air balloon is 801.9L.
As the temperature of the hot air balloon on the table is increased, the its volume also increases.
<h3>Charle's law</h3>
Charle's law states that the volume of an ideal gas is directly proportional to the absolute temperature provided pressure is kept at constant.
It is expressed as;
V₁/T₁ = V₂/T₂
Given the data in the question;
- Initial temperature T₁ = 26.7°C = 299.85K
- Final temperature T₂ = 48.3°C = 321.45K
To calculate the new volume we subtsitute our given values into the expression above.
V₁T₂ = V₂T₁
V₂ = V₁T₂ / T₁
V₂ = ( 748L × 321.45K ) / 299.85K
V₂ = 240444.6LK / 299.85K
V₂ = 801.9L
The new volume of the hot air balloon is 801.9L.
As the temperature of the hot air balloon on the table is increased, the its volume also increases.

The mass number of the daughter atom formed from the alpha decay of a certain radioactive atom that has 90 protons and 142 neutrons is 228.
<h3>What is alpha decay?</h3>
Alpha decay of a radioactive material is the release of an alpha particle that posseses mass number of 4 and atomic number of 2.
According to this question, a certain radioactive atom that has 90 protons and 142 neutron undergoes alpha decay. This means that the mass number of the daughter atom will be as follows:
Mass number of radioactive atom = 142 + 90 = 232
Mass number of daughter atom = 232 - 4 = 228
Therefore, the mass number of the daughter atom formed from the alpha decay of a certain radioactive atom that has 90 protons and 142 neutrons is 228.
