What happens if a hydrogen car catches fire? The vehicles are designed with a thermal pressure relief device (TPRD) on the tank that would discharge if the car was engulfed in a fire. If a fuel leak were to occur, the hydrogen would disperse upward rapidly, and if the TPRD were activated, the tank would […]
What is angular momentum of a particle?
What is angular momentum of a particle? The angular momentum of a rigid object is defined as the product of the moment of inertia and the angular velocity. It is analogous to linear momentum and is subject to the fundamental constraints of the conservation of angular momentum principle if there is no external torque on […]
What is the difference between heat transfer by conduction and convection?
What is the difference between heat transfer by conduction and convection? In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. The heat transfer occurs through a heated solid object. What is the difference between conduction and convection name one medium in? hope this helps. […]
What is the process of changing gas to solid?
What is the process of changing gas to solid? Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation. What are the types of solid solution? There are two classes […]
What are the 2 types of reasoning?
What are the 2 types of reasoning? The two main types of reasoning involved in the discipline of Logic are deductive reasoning and inductive reasoning. Deductive reasoning is an inferential process that supports a conclusion with certainty. What is the purpose of reasoning? All reasoning has a purpose. All reasoning is an attempt to figure […]
Is it safe to drink from aluminum cans?
Is it safe to drink from aluminum cans? Americans continue to drink canned beverages and eat food from cans lined with BPA. BPA is found in the linings of most canned foods and most aluminum cans, including Coca-Cola products. Now, a new study suggests that even small doses of BPA can significantly increase blood pressure […]
Which would be her first step in balancing an equation?
Which would be her first step in balancing an equation? The first step in balancing a chemical equation is to identify your reactants and your products. Remember, your reactants are on the left side of your equation. The products are on the right side. Why does his teacher ask him to balance the equation by […]
Does Gypsum react to hydrochloric acid?
Does Gypsum react to hydrochloric acid? Does Gypsum react to hydrochloric acid? Gypsum is very soft (softer than a fingernail and so can be scratched by a fingernail). It’s color is typically clear or white, but can take on color from impurities, such as pink or yellow. It will not effervesce (fizz) in dilute HCl […]
Did saber tooth tigers eat humans?

However, there no such evidence that suggests that saber tooth tiger ate humans. What eats a saber tooth tiger? Saber-Toothed Tigers preyed on deer, bison, and woolly mammoths. What were some […]
Is Metal a good insulator?
Is Metal a good insulator? Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Metals are also generally good heat conductors while nonmetals are not. Which metal is the best insulator? As you can see, out of […]
