Your friend the archaeologist, who studies the ancient human past, has asked you to find a numerical date for some hominid artif

acts found buried by ash from a volcanic eruption. To do this, you can use carbon-14 dating, which has a half-life of 5,730 years, or uranium-238, which has a half-life of 4.5 billion years. Based on their half-lives, which isotopic dating system will give your friend the most accurate numerical age

The ideal gas constant, R has several different values that could be used. Which quantity causes these differences? pressure tem
Blababa [14]

Answer : The correct option is, pressure.

Explanation :

The ideal gas equation is,

PV=nRT

where,

P = pressure of the gas

V = volume of the gas

n = number of moles of gas

T = temperature of the gas

R = gas constant

The value of 'R' has several different values which are :

R=0.08205L.atm/mol.K

R=8.3145L.kPa/mol.K

R=8.3145J/mol.K 

R=1.987cal/mol.K

R=0.08314L.bar/mol.K

That means, the value of 'R' is different due the change in the pressure value and all the variables (temperature, volume and moles) are constant.

Hence, the correct option is, pressure.

Okay.. so I guess this is how it goes:

1. Rainforest
2. Temperate deciduous
3. Marine
4. Taiga
5. Tundra

Pls don't completely rely on it, this is my best guess and it's probably right except with Marine life and temperature deciduous. 70% I feel like it would temperate then marine. But check with urself again. Hope this helped..
