A cube measures 3 cm on each side and has a mass of 25 g. What is its density.

Snowcat [4.5K]

Answer:

The density is: $0.926 \,\frac{g}{cm^3}$

Explanation:

Recall that density is defined as the quotient of the object's mass divided by volume. So, we calculate the volume of the 3 cm side cube:

$Vol = (3 \,cm)^3 = 27 \,\,cm^3$

then the density becomes:

$density=\frac{mass}{Vol} =\frac{25}{27} \,\frac{g}{cm^3} \approx 0.926 \,\frac{g}{cm^3}$

A student lifts a basketball to a height of 6 feet and lets the ball drop to the ground. Which statement accurately compares the

Brums [2.3K]

Answer:C

Explanation:

If you are holding the ball that would be the ball would have potential energy since it it not moving. Once you drop the ball it will have kinetic energy since it’s moving. If you drop the ball from 6ft it will have more kinetic since it will have more time to accelerate. If you drop the ball from 2ft then it will have less kinetic energy since it is closer to the ground and won’t have beeping time to accelerate and get rid of the potential energy.

A sample of water is heated at a constant pressure of one atmosphere. Initially, the sample is ice at 260 K, and at the end the

USPshnik [31]

In <u>370 K to 375 K </u>temperature intervals of 5 K, would be the greatest increase in the entropy of the sample.

Option: C

<u>Explanation</u>:

Because the largest difference in molar entropy occurs when a condensed phase (solid/liquid) transforms to the gas phase. Then change in entropy is equal to heat transfer divided by temperature: $\Delta \mathrm{S}=\frac{\Delta Q}{\mathrm{m} T}$ .

According to given ice sample at 260 K, when this solid sample start converting into liquid sample it will gain positive temperature and steam will take place near 373 K (273 K ice temperature + $100^{\circ} \mathrm{C}$ temperature of boiling water). Therefore it’s very obvious that greatest increase in entropy will occur during 370 K – 375 K.
