## Why is sea level 1 atm?

One atmosphere **is equal to the weight of the earth’s atmosphere at sea level** about 14.6 pounds per square inch. If you are at sea level each square inch of your surface is subjected to a force of 14.6 pounds. The pressure increases about one atmosphere for every 10 meters of water depth.

## Is 100 atm a standard condition?

Option C (100 atm) **is not a standard condition** and therefore the correct answer.

## What is the pressure in Torrs?

## What is ATM ITM and OTM in options?

A call option is in the money (ITM) if the market price is above the strike price. A put option is in the money if the market price is below the strike price. An **option can also be out of the money (OTM) or at the money (ATM)**. In-the-money options contracts have higher premiums than other options that are not ITM.

## Why ATM option has highest time value?

Intrinsic value increases the more in the money the option becomes. And at-the-money options have the maximum level of time value but no intrinsic value. Time value is at its highest level when an option is at the money because **the potential for intrinsic value to begin to rise** is greatest at this point.
