PLZ HELPP Cynthia sees that most of the ice in her iced tea has melted. Assuming the water and the ice are at the same temperature, what happened to the particles in her ice? A. The particles have a much greater amount of kinetic energy than before. B. The particles have the same amount of kinetic energy but no longer vibrate in place. C. The particles have had their kinetic energy converted into thermal energy. D. The particles have a higher temperature than before and are moving more freely.

The most correct option here is D

Explanation:

The difference between a solid (ice) and a liquid (water)/gas (steam) is that the particles in a solid is tightly packed (and do not move) as against the particles in liquid which moves quite freely or those in gases that move very freely.

When a solid (for example ice) is subjected to heat, it's particles receives the heat energy, hence have a higher temperature, and starts moving from its compact position which turns the solid into liquid. This was what happened to the ice in Cynthia's iced tea. The ice got/absorbed an increased temperature from the surrounding tea and it's particles began to move (more freely) thereby causing the ice to melt.

answer: h+ its less than oh

explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
