Answer:

The two objects have different volumes.

Explanation:

The density of an object measures how closely packed the mass in the object is. Density of an object is obtained by taking the ratio of the mass of an object and its volume.

Density = mass/volume

The mass present in an object is constant, but the volume may vary with temperature. The volume of substances generally increases with temperature, therefore, density decreases with increase in volume.

Two objects at the same temperature having equal masses may or may not have the same density depending on the volume each object occupy.

If two substances are at the same temperature and have equal masses but different densities, then they must have different volumes.

Answer:

319.15^{o}C[/tex]

Explanation:

When all other variables are constant, we are allowed to use the formula

$\frac{T_{2} }{V_{2} } = \frac{T_{1} }{V_{1} } \\Which can be rewritten as T_{2} = \frac{T_{1} V_{2} }{V_{1} }if you make T2 the subject of the formula. This formula is true only if temperature is in Kelvin not degrees Celsius so T1 must be converted to KelvinNow to calculate T2[tex]T_{2}= \frac{296.15K*3.38.10^{3}L }{1.69.10^{3}L }= 592.3K$ = $319.15^{o} C$

(1) In an experiment for determining the density of water, the following results

Angelina_Jolie [31]

Given parameters:

mass of an empty beaker = 65gm

mass of the beaker and water = 165gm

volume of water = 100cm³

Unknown:

Density of water = ?

Solution:

Density is the mass per unit volume of a substance;

Density = $\frac{mass}{volume}$

To find the mass of the water ;

Mass of water = Mass of beaker and water - mass of an empty beaker

= 165g - 65g

= 100g

So input parameters and solve;

Density = $\frac{100g}{100cm^{3} }$

Density of the water in the beaker = 1g/cm³

A brick has dimensions of 15 cm x 6.0 cm x 12 cm. What is the volume of the brick in cubi meters?

Likurg_2 [28]

Convert all of the units from centimeters to meters by moving the decimal point over to the left two digits.

0.15 m x 0.06 m x 0.12 m

Volume = length x width x height
= 0.15 x 0.06 x 0.12 = 0.00108 m^3
