What is the SI unit of specific heat capacity? Specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kilogram of a substance by 1 kelvin (SI unit of specific heat capacity J kg−1 K−1). What is the specific heat capacity of HCl and NaOH? 4.017 J/g°C. What’s […]
Do light bulbs have high or low resistance?
Do light bulbs have high or low resistance? Incandescent light bulbs have a small filament which when heated begins to glow and emit light. The reason the filament heats up is because it has a high resistance, which means that as electrons move through the filament, they lose a lot of energy. Does a brighter […]

What is real and apparent Expansivity?
What is real and apparent Expansivity? The real (or absolute) expansivity of a liquid is the fraction of its volume by which it expands per kelvin rise in temperature. The apparent expansivity of a liquid is the fraction of its volume by which the liquid appears to expand per kelvin rise in temperature when heated […]

When a positive charge moves in the direction of the electric field what happens?
When a positive charge moves in the direction of the electric field what happens? (1), we see that the direction of the electric field vector at any given point is the same as the direction of the force that the field exerts on a positive test charge located at that point. A positive test charge […]
Why did F1 stop using slicks?
Why did F1 stop using slicks? Formula 1 got rid of the ‘slicks’ and re-introduced ‘grooved’ tyres. The sole purpose of the move was to curb the increasing cornering speeds. Those grooved tyres had three parallel grooves in the front tyres and four parallel grooves in the rear tyres. Are F1 Tyres smooth? ‘Slick’ tyres […]

What is a good insulator?
What is a good insulator? Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of […]
Which animal does not use echolocation?
Which animal does not use echolocation? fruit bats Do bats actually use echolocation? Bats can see as well as humans can, but they have evolved a sophisticated method of using sound that enables them to navigate and find food in the dark called echolocation. Bats produce echolocation by emitting high frequency sound pulses through their […]
