Asealed, insulated calorimeter contains water at 310 k. the surrounding air temperature is 298 k, and the water inside the calorimeter remains at 310 k two hours later. what type of system does the calorimeter attempt to model? a closed system, because energy can enter or leave the system, but matter cannot. a closed system, because neither heat nor matter is entering or leaving the container. an isolated system, because energy can enter or leave the system, but matter cannot. an isolated system, because neither heat nor matter is entering or leaving the container.

An isolated system, because neither heat nor matter is entering or leaving the container.

Explanation:

In a closed system there is no exchange of heat but matter is exchanged. In an isolated system there is no exchange of heat or matter. Here the temperature of water remains constant at 310 K, which means that no heat is exchanged. Also there is no decreases in volume of water the calorimeter after 2 hours, which means that no matter was lost either. Therefore this is an isolated system.

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.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
