Can soda glass be made more resistant to thermal shattering by making it thicker?
Thicker glass can help increase thermal resistance to some extent as it offers more material to absorb and distribute heat, thus reducing thermal shock. However, other factors like the glass composition and manufacturing process also play a significant role in improving thermal resistance. It's not a guaranteed solution but can offer some improvement.
Which electric heater will yield the greater heat output a large resistance in the coil or a small resistance in the coil?
A small resistance in the coil will yield greater heat output in an electric heater. This is because a small resistance allows for a larger current to flow through the coil, which in turn generates more heat due to the increased power dissipation (P = I^2 * R).
How thickness of wire affects brightness of bulb?
Considering that everything else is equal, ie. glass, incoming wire. If you are talking only about the filament wire that is attached between the Two poles inside the bulb, the answer is friction. The thicker the wire the less resistance it will have and will allow more electricity to pass without creating friction, the friction is what causes the wire to heat up and glow.
What kind of sunlight produces more heat than another type of sunlight?
Direct sunlight produces more heat than indirect sunlight. Direct sunlight is more intense and focused, resulting in higher temperatures compared to diffuse or scattered sunlight.
What do bands in a metamorphic rock mean?
The thicker the bands the more intense the heat and pressure conditions were to form the rock. Metamorphic rocks are transformed existing rock types. Thicker bands in the appearance of a metamorphic rock mean that it was made with more intense heat and under greater amounts of pressure.
When wire is thicker its resistance is?
When a wire is made thicker it's resistance decreases.
What is the effect of changing the thickness of the wire?
Changing the thickness of the wire will affect its resistance. Thicker wire has lower resistance, allowing more current to flow through it with less energy loss as heat. Thinner wire has higher resistance, restricting the flow of current and causing more energy to be lost as heat.
What tends to be thicker and more resistance to flow?
Blood
How does the thickness of he loft insulation affect heat loss?
The answer is that the thicker the loft insulation is the more heat loss will be reduced as if it is thicker the more air is trapped between the layers of insulation and thermal energy cannot pass throught trapped air causing it to not leave your howm and therfore hating it Hope this helps C.Turner
How does thickness of insulation effect heat loss?
Thicker insulation reduces heat loss by providing more resistance to heat flow. This means that a thicker layer of insulation can help to maintain a more stable indoor temperature by minimizing the transfer of heat through the building envelope.
Will a thicker or thinner copper wire of the same length allow more electric current to pass through?
A thicker copper wire will allow more electric current to pass through because it has lower electrical resistance. Thinner wires have higher resistance due to increased resistance per unit length. This causes more voltage drop and heat dissipation in the wire, limiting the amount of current that can flow through.
When a wire is made thicker it's resistance is what?
When a wire is made thicker, its resistance decreases. This is because a thicker wire offers more pathways for the flow of electrons, reducing the likelihood of collisions and increasing conductivity.
How does the resistance change as the wire become thicker?
As the wire becomes thicker, the resistance decreases. This is because a thicker wire has more cross-sectional area, allowing more space for electrons to move, resulting in lower resistance to the flow of electrons. Thinner wires have higher resistance due to a smaller cross-sectional area, limiting the flow of electrons.
How does the thickness of wire affect the resistance?
Thicker wire has less resistance than thinner wire due to lower electrical resistance. Thicker wire allows more electrons to flow through it easily, resulting in less opposition to the flow of electric current.
Why the cable to an electric cooker is thicker than the cable to a table light?
Since resistance is inversely proportional to the cross-sectional area of a wire, thicker the wire - lesser the resistance and vice-versa. Now, according to Joule's law of heating, H = I^2 R t; i.e. H (Heat) is directly proportional to the square of I (Current), R(Resistance) and t (time). Whereas, according to Ohm's law, V=IR; i.e. V (Potential difference) is directly proportional to I (Current) and R (Resistance) Comparing both the formulas, we can conclude that H (Heat) needs more Current; I. [H=I^2 R t] Therefore, thicker wire. Hence, the cooker needs a thicker wire while a table light needs a comparatively thinner wire.
Does thickness of wire affect resistance?
Yes, the thickness of a wire affects its resistance. Thicker wires have lower resistance because they allow more current to flow through with less resistance compared to thinner wires. Thicker wires have more cross-sectional area, providing more space for the electrons to move, resulting in lower resistance.
Describe how the electric resistance of a wire changes as the wire becomes longer. How does the resistance change as the wire becomes thicker?
As the wire becomes longer, its resistance increases because there is more material for the electrons to travel through. On the other hand, as the wire becomes thicker, its resistance decreases because there is more space for the electrons to flow, reducing the collisions with the wire material and therefore lowering the resistance.
