Question

15 formula 1 punto convert 66.3 psi to atm. (1 atm = 14.6 psi) round to 1 decimal place. respuesta 16 elección múltiple 1 punto what happens to particles in matter when thermal energy is absorbed? the particles get larger. the average speed of the particles increases. the particles move closer together. strong attractions are formed between particles. 17 elección múltiple 1 punto which phase of matter is represented by the diagram below?

Explanation:

Question 15

Step1: Set up conversion formula

We know that to convert psi to atm, we use the ratio $\frac{\text{atm}}{\text{psi}}$. Given $1\text{ atm}=14.6\text{ psi}$, if we have $x$ atm for $66.3$ psi, then $x=\frac{66.3}{14.6}$.
$x = \frac{66.3}{14.6}$

Step2: Calculate and round

$x=\frac{66.3}{14.6}\approx4.541$. Rounding to 1 - decimal place gives $4.5$.

When thermal energy is absorbed by matter, the kinetic energy of the particles increases. Kinetic energy is related to the speed of the particles. So, the average speed of the particles increases.

In the diagram, the particles are closely - packed but not in a highly ordered, fixed - position like a solid. They can move past one another. This is characteristic of the liquid phase.

Answer:

$4.5$
