Inherited traits are traits that you are born with, they are in one's genes. Natural selection is the concept of "Survival of the Fittest" where only those who have the most beneficial of genetic traits survive to pass on their genetic code onto the next generation.
Does that answer your question?
Answer:
Convection occurs in liquids and gases.
Convection transfers thermal energy.
Convection occurs until all of the fluid is at the same temperature.
Explanation:
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise (like gasses), and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
The girl should first prevent getting scammed. She shouldn’t be sharing any personal information about herself or anybody else. Then to try to prove, she can maybe ask to face time during the day, or asks him out to go somewhere(park,movies,etc.,) but make sure you take someone with you like a trusted adult or someone older, and if he keeps making excuses and denying then it’s pretty clear it’s a catfish.
Answer:
Moles of air 0.1245 mol.
Explanation:
Given data:
Pressure = 1 atm
Temperature = 293 K
Volume = 3 L
Number of moles = ?
Solution:
PV = nRT
R = general gas constant = 0.0821 dm³ atm . K⁻¹ . mol⁻¹
Now we will put the values in equation
PV = nRT
n = PV / RT
n = 1 atm . 3 L / 0.0821 dm³ atm . K⁻¹ . mol⁻¹ . 293 K
n = 3 / 24.1 dm³ atm. mol⁻¹
n = 0.1245 mol
