When you melt ice into water you should have less mass so it cant be a, the density is changed because the ice (a solid) turns into water (a liquid).  I think it should be phase because the volume should change when you melt ice,

Photographs are taken of falling drops of two different liquids: Liquid X Liquid Y Note: the drops have identical volumes. Notic
aliina [53]

Answer:

See explanation

Explanation:

The reason why the droplets are spherical is  the surface area to volume ratio of the falling droplet in a gravitational field. Recall that a sphere has a small surface area to volume ratio.

Between X and Y, one key difference that will define the rate at which the two drops of liquid falls is the viscosity of the fluid. Since the images were not attached, I can not really tell what liquid droplet is more flatter  than the other.

However, the liquid with a greater surface tension will form larger droplets and experience a greater air resistance as the droplet falls. Hence the less the surface tension, the flatter the droplets. Cohesive forces pull molecules of a liquid droplets inwards leading to a more spherical shape and reducing the surface area. Surface tension is therefore the reason why liquids form droplets.

The Prandtl number, Pr, is a dimensionless group important in heat transfer. It is defined as Pr - Cp*mu/k where Cp is the heat
algol [13]

Answer:

The Prandtl number for this example is 14,553.

Explanation:

The Prandlt number is defined as:

Pr=\frac{C_{p}*\mu}{k}

To compute the Prandlt number for this case, is best if we use the same units in every term of the formula.

\mu=1896 \frac{lbm}{ft*h}*\frac{1000 g}{2.205 lbm}*\frac{3.281 ft}{1 m}*\frac{1h}{3600s}  =7938 \frac{g}{m*s}

Now that we have coherent units, we can calculate Pr

Pr=\frac{C_{p}*\mu}{k}=0.66*7938/0.36=14553
