If a graduated cylinder has 28ml of water in it and you add an object which causes the water level to rise to 47ml, what is the
grin007 [14]

Answer:

The object placed in the water has a volume of 19 cm³

Explanation:

<u>Step 1: </u>Data given

volume of the cylinder before adding the object = 28 mL = 28 cm³

After adding an object with volume X the volume rises to 47 mL = 47 cm³

<u>Step 2:</u> Calculate the volume of the object

Volume of the object = Final volume - initial volume

Volume of the object = 47 cm³ (or 47 mL) - 28 cm³ ( or 28 mL) = 19 cm³ (or 19 mL)

The object placed in the water has a volume of 19 cm³

Why do particles with different masses have the same kinetic energy when at the same temperature?
Mandarinka [93]

Answer: Because Kinetic energy depends on temperature and not mass

Explanation:

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

K.E=\frac{3RT}{2}

where K.E = Kinetic energy

R= gas constant

T= temperature in kelvin

It is visible that kinetic energy is dependent on the temperature of the system and not on the mass of the system. Thus particles with different masses have the same kinetic energy when at the same temperature
