Answer:
Rubber:Covalent bonding
Barium sulfide:ionic bonding
Solid xenon: Van daar Waal bond.
Bronze:Metallic bond
Nylon:Covalent bonding
Aluminum phosphate: mixture of ionic and covalent bond
Explanation:
Rubber is mainly composed of isoprene which is predominantly covalent bond
Barium sulphide is predominantly ionic bonding
Is xenon is inert its bond is van daar Waal
Bronze is an alloy of metal usually held by metallic boding
Nylon:covalent bonding
Aluminium phosphate have a mixture of covalent and ionic bond
If your accelerator gets stuck down, do the following:
Shift to neutral.
Apply the brakes.
Keep your eyes on the road and look for a way out.
Warn other drivers by blinking and flashing your hazard lights.
Try to drive the car safely off the road.
Turn off the ignition when you no longer need to change direction.
Answer:
Explanation:
Given.
Thickness of brass plate
Thermal conductivity of brass
Density of brass
Specific heat of brass
Thermal diffusivity of brass
Temperature of oven
The initial temperature
Plate remain in the oven
Heat conduction in the plate is one-dimensional since the plate is large relative to its thickness and there is thermal symmetry about the center plane.
The thermal properties of the plate are constant.
The heat transfer coefficient is constant and uniform over the entire surface.
The Fourier number is > 0.2 so that the one-term approximate solutions (or the transient temperature charts) are applicable (this assumption will be verified).
The Biot number for this process
The constants and corresponding to this Biot are, from 11-2 tables.
The interpolation method used to find the
and
The Fourier number
Therefore, the one-term approximate solution (or the transient temperature charts) is applicable.
Then the temperature at the surface of the plates becomes
