What else can I help you with?
If you stake out a plot of land with a steel tape measure on a hot day will you enclose more or less land than your measurements indicate?
On a hot day the steel tape measure will expand and therefore measure inaccurately. 1cm on the tape measure will maybe be 1.1 cm in actuality so when you measure out a piece of land, you will get more than you bargained for.
After you measure the dimensions of a plot of land with a steel tape on a hot day you return and re measure the same plot on a cold day On which day do you determine the larger area for land?
On a cold day, you will measure a larger area compared to a hot day; metals expand when heated. So on a hot day, your steel ruler will also expand. Whatever you measure on a hot day will be relatively less compared to a cold day.
How do we measure a hot water cylinder?
To measure a hot water cylinder, you typically need to measure its height and diameter. Use a tape measure to determine the height from the floor to the top of the cylinder and the diameter across the widest part. These measurements will help determine the cylinder's capacity and size for replacement or installation purposes.
Which has higher density cold steel or hot steel?
When steel gets hot, it gets slightly larger due to thermal expansion. Since the mass stays the same, and density = mass/volume, it gets (very, very slightly) less dense. So cold steel is more dense than hot steel.
Is hot-rolled steel magnetic?
Yes, hot-rolled steel is magnetic. A few types of steel have limited magnetic properties, but hot rolling is a process by which steel is prepared in a shape for marketing. The hot rolling does not affect the ability of the steel to be attracted to a magnet.
Why does cold rolling take more energy?
when making sheets of steel, the steel is smooshed out flatter and flatter many times until it is as thin as you need it to be. If you do this when the steel is red hot, the metal is very soft and easy to smoosh out. If the steel is not red hot it takes a lot more work = energy, to smoosh it out flat.
How hot is red hot steel?
Red hot
What is better for shipping long distances Tape or hot melt?
Tape by far.
What is HRB in steel?
HRB stands for Rockwell Hardness Scale B, which is a measure of the hardness of a material. In steel, HRB is commonly used to determine the hardness of the material, with a higher HRB value indicating a harder material.
Why does the steel spoon get hot in liquid?
If the liquid is hot,the spoon get heated because steel is an insulator
What is the difference between stainless steel and regular steel?
steel isn't as refined but stainless is well stainless and shiny oohlala hot bod Stainless steel is an alloy (mixture) that has chromium mixed in. The chrome makes ordinary steel harder, more brittle, and more resistant to rust and stains, hense, stainless steel.
Why can steel not be used to make the hot water tank?
You can't use steel to make a hot water tank because steel can rust.
