Which of the following are correct statements

a) 760 torr is equal to 1 atmosphere

b) ${10}^6$ dynes/cm² is called 1 Bar

c) ${10}^5\mathrm{Newtons}/{\mathrm{m}}^2$ is pascal

d) I atmosphere is $1.013\times {10}^5$ dynes $/{\mathrm{m}}^2$

Given data:

To find the correct statements from the given options.

Concept to be used: State of matter

Detailed Solution:

1 $\mathrm{atm}=760\text{ torr }$=1.013 $\times {10}^6$ $\frac{\text{ dynes }}{{\mathrm{cm}}^2}$

And

${10}^6\frac{\text{ dynes }}{{\mathrm{cm}}^2}$ $\text{ is called }$ 1 bar

Therefore, Option B is the correct answer.
