9.8g of water vapor condenses on a soda can at 100.0°C.

Given:
Latent heat of vaporization 2260 J/g
Latent heat of fusion 334 J/g

i) State the phase change for the above process.
ii) Identify the formula used to calculate the heat transferred.
iii) Calculate the amount of energy transferred.
iv) Determine whether energy is released or absorbed.

The volume of the pressurised compartment of a jet aircraft is 340.If the pressurised system has to be maintained at temperature of 18 and a cabin altitude of 10000ft when the aircraft is flying 50000 with a complete change of air every minute. Calculate the mass and volume of air per second which must be delivered to the pressurised compartment

At t = 0.0s, a runner is moving forward (in the positive direction along the x-axis) at a speed of 7.0 m/s. For 2.0 s the runner accelerates to his left at 0.50 m/s2 and backward at 1.0 m/s2. what is the runners position at t = 2.0 s in terms of the component directions (forward/back and left/right)?

A human hair is approximately 56 µm in diameter.
Express this diameter in meters.
Answer in units of m.

Good day I have two questions I need help ASAP.

A car travels 40.0km in 30 minutes then 80.0 km in 40 what is the resultant displacement,avaerage speed and average velocity?

An airplane flies south at the speed of 50 ms in still air what is the resultant velocity of the airplane if the wind is blowing east at 10ms ?

Determine the density of oxygen at 150,000 Pa pressure and Temperature = 27°C. State your answer to nearest 0.001 kg/m3, follow the standard rounding rules in stating answer, and do not attempt to write the units. Take the molar mass of molecular oxygen to be 32 g/mol, R=8.31 JK-1mol-1 and take the absolute zero to be -273°C.

a car is speeding up and has an instantaneous speed of 1.17 m/s when a stopwatch reads 11.6 s. it has a constant acceleration of 2.36 m /s^2. what change in speed occurs between t=11.6 and t=13.0 s?

A.heat is a unit of measurement
B.temperature is a energie
C.temperature is a measurement for intensity of heat

Prove that ‘A reversible process is never attained in practice. It can only be approached’

while passing a slower car on the highway, you accelerate from 19.8 m/s to 27.0 m/s in a time of 10.9s. how far do you travel during this time? what is your magnitude of acceleration?
