This analysis concluded that the unknown was ethylene glycol. This was discovered as the gas was heated to 90 degrees Celsius causing the liquid unknown to evaporate into a gas while recording the mass‚ volume‚ temperature‚ and volume. This provided the mass of 1.6 grams which was found by subtracting the mass of the Erlenmeyer flask‚ aluminum cover‚ and rubber band from the mass of the Erlenmeyer flask‚ aluminum cover and rubber band and unknown gas after heating. Then the temperature of the gas

Plant Growth and Development Define growth‚ differentiation‚ development‚ dedifferentiation‚ redifferentiation‚ determinate growth‚ meristem and growth rate. (a) Growth It is an irreversible and permanent process‚ accomplished by an increase in the size of an organ or organ parts or even of an individual cell. (b) Differentiation It is a process in which the cells derived from the apical meristem (root and shoot apex) and the cambium undergo structural changes in the cell wall and the protoplasm

WHAT IS FUMIGATION? Fumigation is the process by which a lethal chemical is released into an enclosed area to eliminate an infestation of pests. This process may be used in order to rid a home or other structure of insects such as termites or roaches‚ but it may also be used when products are being processed for export or import in order to rid the goods of exotic pests and organisms. Fumigants are a unique and particularly valuable group of pesticides that can kill insects where no other form

Flowering plants grow in a wide variety of habitats and environments. They can go from germination of a seed to a mature plant producing new seeds in as little as a month or as long as 150 years. Plants that complete their life cycle in a single season are called annuals; while biennials take two years; and perennials may take several to many years to go from germinated seed to producing new seeds. Fruits and Seeds The taste of a fruit depends on the combinations present in it. Normally
