Answer:
D. Opening the front door in winter to filter and clean warm ai
Explanation:
All of the following are examples of ways to improve energy efficiency of heating systems, except _______.
A. Closing off rooms that aren’t in use.
B. Frequently cleaning the furnace filter.
C. Fixing cracks in the walls and floor.
D. Opening the front door in winter to filter and clean warm air
for an heating systems it is better to keep the front door shut so that all the heat energy does not escape outside.
when heat energy is within a closed system ,it can still be utilized to keep the inhabitants warm otherwise there will be an exchange with the cold from winter fall outside the air, and the heating system's efficiency will be reduced
Answer : The volume of one mole of gas is dependent of temperature and pressure.
Explanation:
At <span><span>0o</span>Cand1atm</span> one mole of an ideal gas would be <span>≈22.4L</span>, which is the same as <span>22.4d<span>m3</span></span>
If you double the pressure, the same amount (mole) of gas would take up only half the space.
If the temperature changes (and pressure stays constant), the gas will expand or contract by about <span>1%/<span>3o</span></span>.
Answer:
i think its the golgi body tbh
Explanation:
hope this helps
To solve the problem it is necessary to apply the equations related to the Poiseuilles laminar flow law, with which the stationary laminar flow ΦV of an incompressible and uniformly viscous liquid (also called Newtonian fluid) can be determined through a cylindrical tube of constant circular section. Mathematically this can be expressed:
Where:
are the viscosities of the concrete before and after the increase
l = Length of the vessel
= Radio of the vessel before and after the increase
= Change in the pressure
The rates of flow before and after he increase
Our values are given as:
10 times her resting rate
95% of its normal value
Increase of 50%
Plugging known information to get
Therefore the factor of average radio of her blood vessels increased is 1.589 the initial factor after the increase.
Answer:
Solid at room temperature
Explanation
Since these elements are metals they must be said at room temperature
