Which phase of matter is made up of particles that are packed relatively close together, with an indefinite shape but a definite

volume? gas liquid plasma solid?
Physics
1 answer:
Bezzdna [24]3 years ago
5 0

property of gas

gas molecules are very loosely bonded with each other so the force between the molecules is very weak

Due to this weak force the molecules of gas can attain any shape and any volume.

So gas moles have no finite shape and no finite volume

Property of Solids

Solids are tightly packed and having very strong bond between the molecules

If all molecules are tightly bonded then they have always a finite shape and finite volume so in this case we can not change the volume or shape of the solids as it is fixed.

Property of Liquids

Liquid molecules are moderately bonded together and since the force is more than the force between the gas molecules so liquids have finite volume but indefinite shape

liquid attains the shape of the container but its volume is fixed

So in above all examples Liquid is correct answer

Underground water is being pumped into a pool whose cross section is 3 m x 4 m while water is discharged through a 0.076m-diamet
Svetllana [295]
Given:

Area of pool = 3m×4m
Diameter of orifice = 0.076m
Outlet Velocity = 6.3m/s
Accumulation velocity = 1.5cm/min

Required:

Inlet flowrate

Solution:

The problem can be solved by this general formula.

Accumulation = Inlet flowrate - Outlet flowrate
Accumulation velocity × Area of pool = Inlet flowrate - Outlet velocity × Area of orifice

First, we need to convert the units of the accumulation velocity into m/s to be consistent.

Accumulation velocity = 1.5cm/min × (1min/60s)×(1m/100cm)
Accumulation velocity = 0.00025 m/s

We then calculate the area of the pool and the area of the orifice by:

Area of pool = 3 × 4 m²
Area of pool = 12m²

Area of orifice = πd²/4 = π(0.076m)²/4
Area of orifice = 0.00454m²

Since we have all we need, we plug in the values to the general equation earlier

Accumulation velocity × Area of pool = Inlet flowrate - Outlet velocity × Area of orifice

0.00025 m/s × 12m² = Inlet flowrate - 6.3m/s × 0.00454m²

Transposing terms,

Inlet flowrate = 0.316 m³/s

Answer:

<em>UP</em>

Explanation:

heat flows from higher level to lower level

( higher concentration to lower concentration )

and since temperature in above block is less than the lower block, the heat will flow from lower block to higher block .

( Up )
