A sample of an unknown solid is found to have a volume of 24.3 cm3 and a mass of
Anna71 [15]
<h2>Answer:  8.93 g/cm³</h2>

<h3>Explanation:</h3>

Density = mass ÷ volume

            = 217.0 g ÷ 24.3 cm³

            = 8.93 g/cm³

<h3>∴ the unknown sample of mass 217.0 grams and volume of 24.3 cm³ has a density of 8.93 g/cm³. </h3>

PLEASE ANSWER
yuradex [85]

D. Even though the temperature is the same, container B has more thermal energy, since it has more liquid than container A.

<u>Explanation: </u>

Whenever there is an increase in the volume of the pink liquid, it is due to the increase in temperature.

When the temperature increases, the molecules move farther apart as much as possible.

When the molecules moves apart from each other and collide with each other, so that its kinetic energy also increases, So thermal energy of the container B is more compared to the container A.

An aluminum can holds 350 mL of gas at 0 C and 1.0 atm. what is the new volume if the can is heated to 10 C and the pressure ins
Mademuasel [1]

Answer:

Final volume of the gas is 4.837mL

Explanation:

Initial volume (V1) = 350mL = 0.35L

Initial temperature (T1) = 0°C = (0 + 273.15)k = 273.15k

Initial pressure (P1) = 1.0atm

Final volume (V2) = ?

Final temperature (T2) = 10°C = (10 + 273.15)k = 283.15K

Final pressure (P2) = 75atm

To solve this question, we'll have to use combined gas equation which is the combination of all gas law I.e Charle's laws, Boyle's law, Pressure law etc.

According to combined gas equation,

(P1 × V1) / T1 = (P2 × V2) / T2

Make V2 the subject of formula,

V2 = (P1 × V1 × T2) / (P2 × T1)

V2 = (1.0 × 0.35 × 283.15) / (75 × 273.15)

V2 = 99.1025 / 20,486.25

V2 = 0.004837L

V2 = 4.837mL

The final volume of the gas is 4.837mL

Why is a Container important to the sustainability of your hydroponic system?
sergij07 [2.7K]
Hydroponics is more than just another way to grow plants–the technology has the potential to change how we engage with food cultivation as a whole! For the first time since humans started tilling the land, modern hydroponics technology frees us from the soil beneath our feet, allowing us to bring food production indoors where we can layer in additional climate and lighting controls. The result is an ability to grow food anytime, anywhere in the world.
