Why cold water don't fog mirrors?
Cold water doesn't fog mirrors because fogging occurs when warm, moisture-laden air comes into contact with a cooler surface, causing the moisture to condense into tiny water droplets. If the mirror is cold, it can cool the air immediately adjacent to it, but if the mirror itself is cold and the surrounding air is also cool, there isn’t enough temperature difference to create condensation. Consequently, the moisture remains in the air rather than forming fog on the mirror's surface.
Why don't objects need to be streamlined in space?
In space, there is no atmosphere or air resistance, so objects do not encounter drag forces that can slow them down. This means that streamlined shapes, which reduce air resistance on Earth, are unnecessary in the vacuum of space. Objects can travel freely without the need for aerodynamic designs, making their shapes less critical for movement. However, for operations involving re-entry into an atmosphere, streamlining becomes essential again to manage heat and drag.
Why the glass get frosty?
Glass gets frosty due to the condensation of moisture on its surface, often resulting from a temperature difference between the glass and the surrounding air. When warm, humid air comes into contact with the cooler glass, the moisture in the air condenses into tiny water droplets, creating a foggy appearance. Frost can also form when the temperature drops below freezing, causing water vapor to crystallize on the glass. This effect is commonly observed on windows and glasses in cold weather or when warm drinks are placed in cold containers.
Why should you never weigh objects while still hot?
A warm or hot object will create a convection current in the air around the balance pan. This fluctuating force reduces the air pressure on the balance pan and can make it difficult to obtain a stable reading.
Witch is easier to play obeo or the flute?
The oboe is generally regarded as harder to play than the flute because of the air pressure that is required when blowing into an oboe reed and because of the sensitivity of the oboe reed regarding a proper amount of moisture.

How is hair affected by air moisture?
Hair can become frizzy and unruly in humid conditions due to the absorption of moisture from the air. On the other hand, in dry conditions, hair may feel brittle and lackluster as moisture is drawn away from the hair shaft. It is important to manage hair with appropriate products to help mitigate the effects of varying air moisture levels.
Does iron placed in an air conditioned room rust?
Iron can still rust in an air conditioned room if there is moisture present in the air. Air conditioning can reduce humidity levels, but if the room is not well-sealed or if there are other sources of moisture, rust can still occur. It's important to keep iron objects dry to prevent rusting.

What types of objects are most strongly affected by air resistance?
Objects with large surface areas and shapes that are not streamlined are most strongly affected by air resistance. For example, a flat surface such as a parachute or a square sheet of paper will experience greater air resistance compared to a streamlined shape like a sphere or an arrow.
The path of flying objects?
The path of flying objects is typically affected by factors such as gravity, air resistance, and initial velocity. Objects follow a curved path known as a parabolic trajectory due to the influence of gravity. Other factors like wind speed and direction can also affect the path of flying objects.
What is true about air pressure acting on an object?
Air pressure is the force exerted by the weight of the air above an object. It acts in all directions and can impact objects by pushing or compressing them. Differences in air pressure can cause objects to move or be affected in various ways.
Which of the following objects would be most affected by air resistance when falling?
The object with the largest surface area relative to its mass would be most affected by air resistance when falling. This means objects with a larger surface area, such as a feather or a sheet of paper, would experience more air resistance compared to objects with smaller surface areas, like a dense metal ball.
What is meant by free falling objects?
Free falling objects are those that are only under the influence of gravity, with no other external forces acting on them. As a result, these objects accelerate towards the ground at a rate of 9.81 m/s² (on Earth) and do not experience air resistance. The motion of free falling objects can be described using the equations of motion.
What is moisture that falls from to the ground?
Moisture that falls from the ground is called dew. Dew forms when water vapor in the air condenses on the surface of objects on the ground during the night when temperatures drop.
What type of air hold moisture best?
Warm air generally holds moisture better than cold air. This is because warmer air has a higher capacity for water vapor, so it can hold more moisture before reaching saturation. Cold air, on the other hand, has a lower capacity for moisture and can become saturated more quickly.
What instruments measure air moisture?
Hygrometers are instruments used to measure air moisture. They can either be mechanical or electronic devices that provide readings of humidity levels in the air. Other instruments like psychrometers and hygrometric tables are also used to measure air moisture.
