What is a good thermal conductivity? It is measured in Watts per Metre Kelvin (W/mK). To allow you to get a feel of insulating materials – their thermal conductivity varies between about 0.008 W/mK for vacuum insulated panels (so these are the best, but very expensive!) to about 0.061 W/mK for some types of wood […]

Can a school expel a student for hate speech?
Can a school expel a student for hate speech? In a victory for free speech, the U.S. Court of Appeals for the Third Circuit issued a historic decision in the case, holding that the school’s limited power to punish students for disruptive speech doesn’t apply to off-campus speech, even if that speech is shared on […]

Who is the better parent mom or dad?
Who is the better parent mom or dad? A study of 18,000 people shows that fathers experience more well-being from parenthood than mothers. Past studies have considered whether people with children have greater well-being than people without children. They do. Is a mom more important than a dad? In a long-term analysis of 36 international […]
What happens when energy is transferred into a liquid?
What happens when energy is transferred into a liquid? Evaporation occurs at the surface of a liquid. Evaporation happens on the surface and is a much slower process. By adding energy you cause the molecules to move faster and break away from the others. The temperature that evaporation occurs is called the vaporization point or […]
What happens to the graph of a line when the slope is negative?
What happens to the graph of a line when the slope is negative? A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the […]
Can you increase gravity without increasing mass?
Can you increase gravity without increasing mass? Thanks! Dear all, actually, increasing the gravity can only be done by adding mass. If you are on the inside of a rotating object, the centrifugal force can added to the gravitational one and it feels like enhanced gravity, but the gravitational force itself does not change. Is […]
What was formed by destructive forces?
What was formed by destructive forces? of landforms. Landforms are a result of a combination of constructive and destructive forces. Collection and analysis of data indicates that constructive forces include crustal deformation, faulting, volcanic eruption and deposition of sediment, while destructive forces include weathering and erosion. What is the definition of destructive forces? A destructive […]
Is thermometer mercury dangerous?
Is thermometer mercury dangerous? The small silvery ball in a mercury thermometer can be dangerous if the glass breaks and the mercury is not cleaned up properly. The mercury will evaporate and can contaminate the surrounding air and become toxic to humans and wildlife. Each thermometer contains about . Can mercury leak from thermometer? If […]
