What else can I help you with?
Metal lids on glass jars can often be loosened by running hot water over them. Why does that work?
Running hot water over a metal lid on a glass jar causes the metal to expand slightly due to the heat, which can help break the seal it has with the glass jar. This expansion makes it easier to twist the lid open.
What do water and oxygen do to metal?
Water can cause metal to rust or corrode by inducing oxidation reactions. Oxygen plays a key role in this process as it reacts with the metal surface, forming metal oxides that weaken the material over time.
Why do you have to heat alcohol or ethanol over water and not over an open flame?
Heating alcohol or ethanol over water helps maintain a more controlled and even heat distribution, reducing the risk of accidental fires or explosions that can occur when heating directly over an open flame. The water provides a buffer and ensures that the alcohol is heated gently and evenly.
Does chlorine evaporate from tap water?
Yes, chlorine can evaporate from tap water over time, especially if the water is left out in an open container.
What will happen if you put ferrous metal in water?
Ferrous metals, such as iron, will react with water to form iron oxide (rust). This reaction will cause the metal to corrode and weaken over time. It is important to protect ferrous metals from exposure to water to prevent corrosion.
Metal lids on glass jars can often be loosened by running hot water over them. Why does that work?
Running hot water over a metal lid on a glass jar causes the metal to expand slightly due to the heat, which can help break the seal it has with the glass jar. This expansion makes it easier to twist the lid open.
Explain why running some hot water over the lid might make it easier to open?
Heat makes metal expand so running hot water over a lid allows it to become slightly bigger, therefore loosening it and making it easier to turn off the jar.
Why dows running hot water over a tight lid make a jar easier to open?
Running hot water over a tight lid causes the metal to expand slightly and lose some of its grip on the jar, making it easier to open. The heat loosens the seal between the metal lid and the glass jar, reducing the friction and making it easier to break the seal.
Can a father have over night visitation if he has not running water or plumbing in his home?

A deep ditch carved over time by running water is called what?
A deep ditch carved over time by running water is called a ravine.
What property of substance can be used to open a tight metal lid from a glass bottle?
Metal water bottles are considered to be more environmentally friendly than single-use plastic bottles. It's because these are reusable and can last for a long time, reducing the need for single-use plastics that contribute to environmental pollution. Also, the production of metal bottles like contigo metal water bottle has a lower environmental impact compared to the manufacturing of plastic bottles. for more visit - destinationupfittersdotcom
How could you test if argon is a non metal?
You first get a bowl of tap water, get a test tube with the argon in it. Take out the cork screw out of the test tube. Get a splint put it over the test tube when you open it and it it pops that means it is a metal
What do you do when you can't open a jar?
run lid over hot water and open with a cloth over lid.
If you can run hot water over a lid it gets loose and you can open it how is that possible?
It works best with a metal lid on glass. When the metal lid gets hot from the hot water it expands. The glass doesn't expand as much as metal so the tight seal that the lid had on the glass gets loosened as the lid gets slightly larger.
What is the term given for water running over the ground?
It's called surface water.
What is one idea you have as to how you could conserve water?
One idea of how you can conserve water is to not leave it running for days. Some people leaves water running for over an hour each day.
Can water dent or bend metal?
Under normal circumstances, water cannot dent or bend metal. However, water can cause metal to corrode or rust over time, depending on the type of metal. This corrosion weakens the metal and may eventually lead to deformation or damage.
