What happens when you remove heat from a metal rod?
What happens when you remove heat from a metal rod? After the heat source is removed, the bar starts to cool down immediately. However, this only means the average temperature of the bar is decreasing. As long as there is a temperature difference, heat will continue to flow from the hotter to the colder regions. […]
Can a torpedo sink an aircraft carrier?
Can a torpedo sink an aircraft carrier? During World War II, submarine and aircraft-dropped torpedoes sank hundreds of merchant ships and warships. Unlike the numerous aerial bombs or cannon shells required to sink large warships, just one or two torpedo hits could and sometimes did suffice to sink huge aircraft carriers and battleships. Could a […]
What is critical angle with diagram?
What is critical angle with diagram? Include a ray diagram to explain the concept. The critical angle occurs when the angle of incidence where the angle of refraction is 90°. The light must travel from an optically more dense medium to an optically less dense medium. What is the value of refractive index and critical […]

How do you convert Fahrenheit to Celsius in chemistry?
How do you convert Fahrenheit to Celsius in chemistry? In other words, if you’d like to convert a temperature reading in Fahrenheit to Celsius: Start with the temperature in Fahrenheit (e.g., 100 degrees). Subtract 32 from this figure (e.g., 100 – 32 = 68). Divide your answer by 1.8 (e.g., 68 / 1.8 = 37.78) […]
