A piston-cylinder chamber contains 0.1 m3 of 10 kg R-134a in a saturated liquid-vapor mixture state at 10 °C. It is heated at co
vaieri [72.5K]

Answer:

(A) 10132.5Pa

(B)531kJ of energy

Explanation:

This is an isothermal process. Assuming ideal gas behaviour then the relation P1V1 = P2V2 holds.

Given

m = 10kg = 10000g, V1 = 0.1m³, V2 = 1.0m³

P1 = 101325Pa. M = 102.03g/mol

P2 = P1 × V1 /V2 = 101325 × 0.1 / 1 = 10132.5Pa

(B) Energy is transfered by the r134a in the form of thw work done in in expansion

W = nRTIn(V2/V1)

n = m / M = 10000/102.03 = 98.01mols

W = 98.01 × 8.314 × 283 ×ln(1.0/0.1)

= 531kJ.

A car is travelling at 50km/h. After 12 seconds, it is now travelling at 60km/h. What is the car’s acceleration
astra-53 [7]

Acceleration = (change in speed) / (time for the change)

Change in speed = (ending speed) - (starting speed)

Change in speed = (60 km/hr) - (50 km/hr) = 10 km/hr

Time for the change = 12 sec

Acceleration = (10 km/hr) / (12 sec)

Acceleration = 0.8333 km/hr-sec

Convert to a unit that we can understand:

Acceleration = (0.8333 km/hr-sec)x(1000 m/km)x(hr/3600sec)

Acceleration = (833.3 / 3600) (m-hr / hr-sec²)

Acceleration = (833.3 / 3600) (m/s²)

<em>Acceleration = 0.231 m/s² </em> or  0.833 km/hr-sec²
