D, water vapor. Gaseous state would have more kinetic energy, they are moving faster. If you have to compare the same state, then higher temperature would have the higher kinetic energy. But if you have solid and liquid at the same temperature - then liquid would have more.
Answer: The handle of a frying pan on the stove
Explanation: Convection is the heat transfer done by the movement of a fluid, or the molecules on it. This can happen by the change on density from fluids, when a fluid tempeture rise, it expands, rising his volumen and decreasing his density. When this happens the fluid becomes lighter, so it moves.
The handle of a frying pan gets hotter but no molecular movement is done. It is between the same material there is a energy transfer from the source to the rest of the pan. This is called Conduction.
The answer is A. Mass is constant, height and width won’t change. So that leaves weight.
Answer:
Induced emf of the wire is 6.36 Volts.
Explanation:
It is given that,
Length of the wire, l = 75 cm = 0.75 m
Magnetic field, B = 0.53 T
Velocity, v = 16 m/s
The wire is moving straight up in the magnetic field. So, an emf is induced in the wire. It is given by :
So, the induced emf of the wire is 6.36 V. Hence, the correct option is (b) "6.36 V".
Answer:
V₂=4.57 x 10³ L
Explanation:
Given that
V₁= 2.88 x 10³ L
P₁=722 mm Hg
T₁ = 19°C
T₁ =292 K
P₂=339 mm Hg
T₂= - 55°C
T₂=218 K
Lets take final volume = V₂
We know that ideal gas equation
PV = m R T
By applying mass conservation
V₂=4.57 x 10³ L
Therefore volume will be 4.57 x 10³ L
