A gas has a volume of 543 ml. at a temperature of 75.0°C. What volume will the gas occupy at 20.2°C?
alexandr1967 [171]

Answer:

V₂ = 457.49 mL

Explanation:

Given that,

Initial volume, V_1=543\ mL

Initial temperature, T_1=75^{\circ} C=75+273=348\ K

Final temperature, T_2=20.2^{\circ} C=20.2+273=293.2\ K

We need to find the final volume of the gas. The relation between the volume and the temperature of the gas is given by :

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

Put the respected values,

V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{543\times 293.2}{348}\\\\V_2=457.49\ mL

So, the final volume of the gas is equal to 457.49 mL.

A sample of aluminum metal absorbs 10.3 j of heat, upon which the temperature of the sample increases from 23.2 °c to 30.5 °c. s
stira [4]
<span>1.6 g First, calculate the change in temperature. 30.5 - 23.2 = 7.3 K Now we have 3 pieces of data, the units involved are K, J/(g K), and J. We wish to create a result with the units being g. Let's start with the specific heat. 0.90 J/(g K) Now let's cancel out the K by multiplying by our data with K 0.90 J/(g K) * 7.3 K = 6.57 J/g Now we want to cancel out the J and get g on top. We can do that by dividing the J value we have by the calculated value above. So 10.3 J / 6.57 J/g = 1.567732116 g Rounding to 2 significant figures gives us a mass of 1.6 g Remember, for most problems, simply look at the units you have and what you desire for the units in the final result. By paying attention to this, the math operations you need are pretty automatic.</span>
