How is the unit bar related to the S.I. unit pascal?
How is the unit bar related to the S.I. unit pascal?
- A. \( 1 b a r=10^{5} \) pascal
- B. 1pascal = 10 \( ^{5} \) bar
- C. \( 1 b a r=10 \) pascal
- D. \( 1 b a r=1 \) pascal
Step-by-step solution
The bar is a unit of pressure defined as 100,000 pascals (Pa). Therefore, 1 bar equals 10^5 Pa. Option A correctly states this relationship, while the others are incorrect.
