How high can a helium balloon go? 9,000 meters What happens to a helium balloon in space? One is that atmospheric pressure is dramatically reduced at high altitudes, so a helium balloon expands as it rises and eventually explodes. But the elasticity of rubber decreases at very low temperatures so it is possible that helium […]
Can a load be a resistor?
Can a load be a resistor? Devices called resistors are built to provide precise amounts of resistance in electric circuits. Any device that performs some useful task with electric power is generally known as a load. Sometimes resistor symbols are used in schematic diagrams to designate a non-specific load, rather than an actual resistor. What […]
Can you see a molecule?
Can you see a molecule? This, believe it or not, is a microscope. It can help us see very small particles like molecules by feeling the particle with the tip of its needle. These very powerful microscopes are called atomic force microscopes, because they can see things by feeling the forces between atoms. … What […]
What does the G in reaction I represent?
What does the G in reaction I represent? The (aq) sign stands for aqueous in water and means the compound is dissolved in water. Finally, the (g) sign means that the compound is a gas. Coefficients are used in all chemical equations to show the relative amounts of each substance present. What does the subscript […]
How does oxygen turn into ion?
How does oxygen turn into ion? Oxygen, O. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-. Can oxygen ion be positive? Thus, an energetic electron passing near or through an oxygen molecule, […]
Who will be fined for not wearing a seatbelt?
Who will be fined for not wearing a seatbelt? By law, drivers must ensure that they and any other passenger in the vehicle are wearing their seatbelt, regardless of their age. However, passengers are still accountable, as both drivers and passengers aged 16 years and over can be fined if they fail to wear a […]
What happens when a warm and cold air mass collide?
What happens when a warm and cold air mass collide? When a warm air mass meets a cold air mass, the warm air rises since it is lighter. As it rises, the warm air cools rapidly. This configuration, called a cold front, gives rise to cumulonimbus clouds, often associated with heavy precipitation and storms. What […]
What is a good analogy?
What is a good analogy? A good analogy is a compromise between two conflicting goals: familiarity and representativeness. Good analogies are familiar. They express an abstract idea in terms of a familiar one. But a good analogy doesn’t need to be concrete, it only needs to be expressed in terms of an idea you already […]
How can you tell if MAP sensor is bad?
How can you tell if MAP sensor is bad? What to look out for in a failing MAP sensor Rich air-fuel ratio: Look for rough idle, poor fuel economy, slow acceleration and a strong smell of gasoline (especially at idle) Lean air-fuel ratio: Look for surging, stalling, lack of power, hesitation on acceleration, backfiring through […]
Who did Orion love?
