Acollege student is working on her physics homework in her dorm room. her room contains a total of 6.0 x10^26 gas molecules. as she works, her body is converting chemical energy into thermal energy at a rate of 125 w. if her dorm room were an isolated system (dorm rooms can certainly feel like that) and if all of this thermal energy were transferred to the air in the room, by how much would the temperature increase in 19min ?

Explanation:

given,

total gas molecule , N = 6 x 10²⁶

Power,P = 125 W

Δ t = 19 min = 19 x 60 s

Δ T = ?

Power,

we now,

where as, k_b = 1.38 x 10⁻²³ J/K

The increase in temperature is equal to

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

the answer to this is proletariats.

hope this : )
