For grass stain, pretreat with stain remover or liquid laundry detergent with hot water or use the dilute white vinegar and flush with cold water. [16] For grease stain, soap the stain with the work liquid dish soap and a clean cloth. Then wash it with hot water. [16] For Ink stain, wash the stain with stain remover and wash it in the laundry.
For stain removal, conventional household washing machines use heated water, as this increases the solubility of stains. However, heating the water to the required temperature uses a considerable amount of energy; energy usage can be reduced by using detergent enzymes which perform well in cold water, allowing low-temperature washes and ...
There is no chief underlying chemical reason why club soda would be superior to plain water in stain removal. [8] Glycerine This can be used to soften "set" stains, especially on wool and non-water-washable fabrics. [3] Boiling water This can be used to take out fruit juice stains. Hot water activates the detergent and as well as sanitize the ...
Fill the pan with warm water and mild dish soap, allowing it to sit for 15-20 minutes. This allows time for the stuck pieces to absorb the water, soften, and become easier to loosen. Then begin ...
However, what is a "standard" laboratory temperature and pressure is inevitably geography-bound, given that different parts of the world differ in climate, altitude and the degree of use of heat/cooling in the workplace. For example, schools in New South Wales, Australia use 25 °C at 100 kPa for standard laboratory conditions. [47]

The European Pharmacopoeia defines it as being simply 15 to 25 °C (59 to 77 °F), and the Japanese Pharmacopeia defines "ordinary temperature" as 15 to 25 °C (59 to 77 °F), with room temperature being 1 to 30 °C (34 to 86 °F). [18] [19] Merriam-Webster gives as a medical definition a range of 15 to 25 °C (59 to 77 °F) as being suitable ...
For clarity, he then described a hypothetical, but realistic variant of the experiment: If equal masses of 100 °F water and 150 °F mercury are mixed, the water temperature increases by 1 ° and the mercury temperature decreases by 49 ° (both arriving at 101 °F), even though the heat gained by the water and lost by the mercury is the same.
