Cryoskeleton effect is a decrease in the coagulation temperature of solutions, for example under the influence of salt addition. Therefore saltwater sea water freezes at lower temperatures than sweet and sprinkles in winter asphalt.Created by: Katarzyna Dąbrowskavery hard 38% Increasing the boiling temperatureIncreasing the boiling temperature871Decreasing the boiling temperatureDecreasing the boiling temperature1741Increasing the solidify temperatureIncreasing the solidify temperature2064Decreasing the solidify temperatureDecreasing the solidify temperature2868water riddles » What can we measure in Centimorgans?The The distance between chromosome positions. In genetics, a centimorgan (abbreviated cM) is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01. It is often used to infer distance along a chromosome. However, It is not a true physical distance.Created by: Katarzyna Dąbrowskahard 48% The distance between molecules in solutionThe distance between molecules in solution494The length of chemical bondsThe length of chemical bonds508the The distance between chromosome positionsthe The distance between chromosome positions1482The length of protein structuresThe length of protein structures541genetics riddles » Who discovered the rubber vulcanization process?Charles Goodyear for many years improved the method of hardening the rubber.

Dry ice is the solid form of carbon dioxide. In temperatures above −78.5 °C (−109.3 °F) it will not melt but sublimate, that means transforming straight from solid form into gas one without liquid phase.Created by: Justa87hard 45% H₂OH₂O755CO₂CO₂2577CH₄CH₄969HCOOHHCOOH1309nature riddles » What is dry ice?Solidified CO2. Dry ice is used in refrigeration. It has an interesting property: it maintains a constant temperature of -78.5C in a warmer environment. This is because dry ice does not melt and sublimes directly into the gaseous form.Created by: Niezgodnavery easy 93% glacierglacier482solidified CO2solidified CO214101legendary alchemical substancelegendary alchemical substance312meringue dessertmeringue dessert210ice riddles » Which substance is the most bitter?Denatonium benzoate.
