If surface tension of water is 75 75 dyne/cm and area of each plate wetted by water is 8\, cm ^ {2} 8cm2 and the distance between the plates is 0.12 \,mm 0.12mm, then the force applied to separate the two plates is JIPMER - 2008 JIPMER Updated On: Jun 7, 2024 10^2 102 dyne 10^4 104 dyne 10^5 … Web10 jan. 2024 · Introduction. Solid culture media, or agar plates, are prone to desiccation. The combination of warm, dry air and limited moisture content to achieve a solid finish leads to inevitable drying out and desiccation. Cracks in the media, a loss of volume or shrinkage away from the sides of the Petri dish are evidence of desiccation.
If two glass plates have water between them and are separated
WebThere is adhesive force acting between the water molecules and the molecules present in the glass. It is much larger than the cohesive force acting between the water molecules. Due to this, a large amount of force is needed to separate the glass together. So, it is difficult to separate the glass plates by direct pull. WebPlacing the two stuck glasses in the hot water, contained in the shallow pan, I then poured ice cold water in the top dish to hopefully and technically contract the top glass dish. Maybe a few ice cubes would stimulate the contraction of the upper glass dish. Not really expecting any results, but certainly trying to continue my reputation as ... firewood inverness

Web14 jan. 2024 · Distance of separation between two plates is 43.89 mm. Explanation: Viscosity of water, η = 0.001 PL = 10⁻³ PL. Velocity, V = 6 m/s. Viscous force, F = 175×10⁻⁵. Length of glass plates, L = 16 cm = 16 x 10⁻² m. Breadth of glass plates, B = 8 cm = 8 x 10⁻² m. Distance of separation between two plates, l = ? Thus, Area of glass ... WebIf two glass plates have water between them and are separated by very small distance (see nig very difficult to pull them apart. It is because the water in between forms … Web1 jul. 2024 · Evaporation rates, evaporation fluxes and contact angles of the meniscus between two glass plates have been experimentally obtained.
