complete the following homework assignment. you will have 5 attempts to improve your score. 1 elección múltiple 1 punto which of the following explains why liquids can flow and solids cannot? solids weigh more than liquids and gases. solids have larger particles than gases and liquids. solids have particles that do not move. solids have strong forces that hold the particles together. 2 fórmula 1 punto a gas occupies 168,0 ml at a temperature of 23,5 °c. what is the volume, in ml, at 76,1 °c? round to 1 decimal
Answer
1.
Brief Explanations:
The ability of liquids to flow and solids not to is due to the strong intermolecular forces in solids that hold particles in fixed positions. Weight and particle - size are not the determining factors, and particles in solids do vibrate but not move freely like in liquids.
Answer:
Solids have strong forces that hold the particles together.

Explanation:
Step1: Convert temperatures to Kelvin
The initial temperature $T_1 = 23.5+273.15=296.65$ K and the final temperature $T_2=76.1 + 273.15=349.25$ K. The initial volume $V_1 = 168.0$ mL.
Step2: Apply Charles's Law ($\frac{V_1}{T_1}=\frac{V_2}{T_2}$)
We can solve for $V_2$ by cross - multiplying: $V_2=\frac{V_1\times T_2}{T_1}$. Substitute the values: $V_2=\frac{168.0\times349.25}{296.65}$.
Step3: Calculate the value of $V_2$
$V_2=\frac{168.0\times349.25}{296.65}=\frac{58674}{296.65}\approx197.8$ mL.
Answer:
197.8
