Answer;

-Acceleration: 10 km/h/s east

Explanation;

-The quantity is either a vector or a scalar. Scalars are quantities that are fully described by a magnitude (or numerical value) alone while Vectors are quantities that are fully described by both a magnitude and a direction.

Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

In this case , a =( v-u)/t ; where a is the acceleration, v is the final velocity, u is the initial velocity and t is time.

      a = (60 - 0)/6

         = 10 km/h/s

Based on the trend in the table, hypothesize what the volume of the sample at 400K would be.
mariarad [96]

Answer: The volume of sample at 400 K is 285cm^3

Explanation:

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

V\propto T     (At constant pressure and number of moles)

{\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1 = initial volume of gas  = 257cm^3

V_2 = final volume of gas  = ?

T_1 = initial temperature of gas  = 360 K

T_2 = final temperature of gas  = 400 K

Putting in the values we get:

{\frac{257}{360}=\frac{V_2}{400}

V_2=285cm^3

Thus volume of sample at 400 K is 285cm^3

During which phase change does the entropy of a sample of H2O increase?
Bezzdna [24]

Answer: 3. H2O(l) -> H2O(g)

Explanation: Entropy is a measure of the randomness or disorder a substance. Gasses have the greatest amount of entropy and solids have the least amount of entropy. The entropy of a sample of H2O increases as liquid water evaporates and changes to a gas.
