Answer:
The condition of very system can be identified by some physical characteristics of the system known as Thermodynamic Property of the system. For example, pressure, temperature, volume, etc.
Explanation:
Thermodynamic properties are nothing but the physical characteristics of any body by which the physical condition of the body can be described. properties describes the different states of a system. They are macroscopic.
Properties are of two types ---
Intensive property
Extensive property
Intensive Property : Those properties of a system which does not depend upon mass of the system are known Intensive property.
For example, pressure, temperature, density,specific volume, etc
Extensive Property : Properties that depends on the mass oh the system is called Extensive properties.
For example, energy, volume, etc.
Answer:
KE= 687.21 BTU
Explanation:
Given that
Mass of car = 2500 lbm
We know that 1 lb=0.45 kg
So the mass of car m =1133.98 kg
Velocity of car= 80 mph
We know that 1 mph =0.44 m/s
So velocity of car = 35.76 m/s
As we know that kinetic energy (KE) is given as follows
Now by putting the values
KE=725.05 KJ
We know that 1 KJ = 0.94 BTU
So KE= 687.21 BTU
Answer:B
Explanation: Dead Grass more flammable than wood and Green grass contains water.
Answer:
it is to warn you about something like a dead end, or maybe where you should slow down because there might be people crossing ahead.
