Explanation:
hope this helps
Based on my information, this would be known to be a "green house" as this, would be as it would be a house known for planting, and etc. But the main part that I wanted to consider would be the fact that it would also be a "closed system" as you would be able to open and close this kind of machine.
Your answer: a greenhouse

Explanation:
41.369
<h3>
Answer:</h3>
1257.45 L
<h3>
Explanation:</h3>
We are given;
- Initial volume of Helium gas, V1 as 806 L
- Initial temperature of Helium gas,T1 as 20.9°C
- Initial pressure of Helium gas, P1 as 753 mmHg
- Pressure of Helium at the altitude 6.8 km, P2 as 417 mmHg
- Temperature of Helium gas at the altitude 6.8 Km, T2 as -19.1°C
But, K = °C + 273.15
Therefore, T1 = 294.05 K and T2 = 254.05 K
- We are required to calculate the new volume of the balloon at 6.8 km.
- To determine the new volume we are going to use the combined gas law.
- According to the combined gas law,
Thus, rearranging the formula;
Therefore, the volume of the balloon at an altitude of 6.8 km is 1257.45 L
<u>Answer:</u> The number of neutrons in boron are 6.
<u>Explanation:</u>
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and number of neutrons present in an atom.
Mass number = Number of neutrons + Number of protons.
We are given:
Mass number = 11
Atomic number of boron = 5
Number of neutrons = Mass number - Atomic number = 11 - 5 = 6
Hence, the number of neutrons in boron are 6.
