A sample of gas at 300 K has a volume of 2.0 liters. At what temperature will the volume decrease to 1.0 liter if the pressure is kept constant?

Answers

Answer 1

Answer:

Answer : The temperature will be, 150 K

Explanation :

Charles' Law : This law states that volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$ (At constant pressure and number of moles)

or,

$(V_1)/(T_1)=(V_2)/(T_2)$

where,

$V_1$ = initial volume of gas = 2.0 L

$V_2$ = final volume of gas = 1.0 L

$T_1$ = initial temperature of gas = 300 K

$T_2$ = final temperature of gas = ?

Now put all the given values in the above formula, we get the final temperature of gas.

$(2.0L)/(300K)=(1.0L)/(T_2)$

$T_2=150K$

Therefore, the temperature will be, 150 K

Answer 2

Answer: pv/t=c
Therefore

v/t=c
2/300=1/t2
t2=150K

The amount of heat transferred from an object depends on all of the following exceptA. the specific heat of the object.
B. the change in temperature the object undergoes.
C. the initial amount of Calories in the object.
D. the mass of the object.

Answers

The amount of heat transferred from an object depends on all of the following except the initial amount of Calories in the object. The answer is letter C. The equation to be used to calculate the heat release when solid melts is the enthalpy of melting. It is represented as H = mCpT where H is the heat released after phase change, m is the mass of the substance, Cp is the specific heat capacity of the substance and T is the change in temperature.
