because you only remove the stuff on an item and not the bacteria
Washing a smear with tap water should be done quickly to prevent the drying of the sample, which can interfere with the visualization of the cells under a microscope. Prolonged exposure to air can cause cellular morphology to change, making it difficult to accurately assess the sample. Additionally, quick washing helps remove excess stains or debris without damaging delicate cellular structures.
Water boils quicker than oil and washing up liquid. This is because water has a lower boiling point compared to oil and washing up liquid. Oil and washing up liquid have higher boiling points, which means it will take longer for them to reach the boiling point compared to water.
The ideal water temperature for washing dishes is between 110°F to 120°F (43°C to 49°C). This temperature range is hot enough to remove grease and grime effectively but still safe for your hands. Water that is too hot can cause injury, while water that is too cold may not clean dishes effectively.
Washing soda is deca hydrated sodium carbonateNa2CO3.10H2O. it is water soluble carbonate.
When water and washing up liquid are mixed, the soap molecules attach to the water molecules due to their different properties. The soap molecules have a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail, which allows them to surround and break up oily or greasy substances in the water, making it easier to remove dirt and grime from surfaces.
If the washing machine only uses hot water, you should use the "hot water" setting for washing your clothes.
Only by water washing.
If you run the washing machine only when it is full, then it should use less water than washing it by hand. If you run the washing machine for one or two garments- you will be using more water than if washing it by hand.
Cold water is best when washing colours. Otherwise, the warm water would only assist in the colours bleeding out ofyour clothes.
Some washing machines have built-in heating elements to heat water, while others rely on hot water supplied from a water heater. Washing machines with a hot water connection may not have a heating element.
Yes, washing machines needs pressurized water even if there is an overhead water storage tank. Usually the owner's manuals have directions on what to do if there is only low or no water pressure available.Ê
If you have trouble getting soap out of your hair after washing, the water is most likely hard water. Hard water can cause build up in the hair which can cast a dull appearance. This can be removed with a chelating shampoo.
Your washing machine may have water in it because it is designed to hold water during certain parts of the washing cycle to help clean your clothes effectively.
The amount of gallons of water a washing machine can hold depends on whether it is a top loader or a front loader. Top loaders can hold about 25 gallons of water. A front loader can only hold about 5 gallons of water.
Hot water is needed for washing dishes and washing cooking implements of various types, however, if necessary, it is possible to heat water in a pot on a stove, if you do not have hot water available from a hot water tap. So in theory, it is possible for a restaurant to continue to function, even without running hot water. It is more difficult, of course.
Wash the acid with water only, no soap is required. Acids are water soluble, and do not need soap to dissolve them.
Yes, most modern washing machines, especially front-loaders, have a heating element inside that allows them to heat water during the washing cycle, even if they are only connected to a cold water supply, enabling you to select different wash temperatures despite only having a cold water input. Key points about washing machine heating: Cold fill design: Many newer machines use a "cold fill" design, meaning they only require a cold water connection and heat the water internally using a heating element. Temperature settings: If your washing machine has temperature settings on the control panel, it likely has a heating element to reach the desired temperature. Top loaders vs. front loaders: Typically, front-loaders are more likely to have a built-in heater compared to top-loaders, which may require a hot water connection for warm washes.
