Answer:

The new temperature of the gas is 604K

Explanation:

Assuming standard temperature and pressure, to calculate the temperature of the gas we use the general gas equation;

Step 1 :write the general gas equation

P1V1/ T1 = P2V2/T2

Step 2: Write out the values, covert the necessary values to the standard values.

P1 = 0.800atm.

V1 = 0.180L

T1 = 29°C = 273 + 29 = 302K

P2 , 3.20atm

V2 = 90mL = 90 * 10^-3L = 0.09L

Step 3: Solve for T2

The new temperature T2 of the gas is:

T2 = P2V2T1/ P1V1

T2 = 3.20 * 0.09 * 302 / 0.800 * 0.180

T2 = 86.976 / 0.144

T2 = 604K

The new temperature is of the gas is 604K.

A person with a body temperature of 37°C holds an ice cube with a temperature of 0°C in a room where the air temperature is 20.°
Arlecino [84]
The answer is (2). Heat always flows down the temperature gradient, from high temperature to low temperature. Therefore, since the person is the warmest, heat flows from the person to both the ice and the air. Additionally, since the air is warmer than the ice, heat flows from the air to the ice.
