Determine a. The Work Done
b. A change in internal energy of 1.00kg of Water when it's All Boil to Steam at 100⁰c. assume a constant pressure of 1.00atm, (1.00kg of steam at 100⁰c has a volume of 1.67m³

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

Both speed and velocity measure how fast something is moving. however, since speed is not a it does not require a(n question 6 options: a) quantity , unit b) magnitude, unit c) scalar, direction d) vector, direction
