Nuclear[edit] Main articles: Nuclear explosion and Effects of nuclear explosions In addition to stellar nuclear explosions‚ a man-made nuclear weapon is a type of explosive weapon that derives its destructive force from nuclear fission or from a combination of fission and fusion. As a result‚ even a nuclear weapon with a small yield is significantly more powerful than the largest conventional explosives available‚ with a single weapon capable of completely destroying an entire city.

Who uses hydroponics? In 2001 it was estimated that 1% of the world’s food is grown using hydroponics. Most commercial crops of tomatoes and many other greenhouse crops are grown hydroponically. Commercial growers use hydroponics because it gives bigger crops for less work. With no soil to use for growing there are no weeds and fewer disease and pest problems. There is also less waste of water and nutrients because these are continuously recycled. All these factors help to reduce the costs of

RHA; same trend for LL and PL. The Linear Shrinkage (LS) decreases as the RHA content increases‚ enhancing the volume stability of the soil. The results obtained from the researches’ work are shown below in Figure 2.7. Figure 2.7: Variation of OMC‚ LL‚ PL‚ PI‚ and LS with RHA content Roy (2014) conducted a research on the soil stabilization using RHA and cement‚ using the soil sample from Burdwan‚ India by disturbed sampling method.

Experiment 2 Behavior of Gases PURPOSE This experiment has two parts. The purpose of part A of the experiment is to determine the atomic mass of a metallic element whereas the purpose of part B of the experiment is to determine the rate of diffusion of both gases hydrogen chloride and ammonia by measuring the distances travelled by the two gases in the same time period. For part A the reaction of the metal with the aqueous acid is as follows: M(s) + n H3O+ -----> M+n(aq) + n/2 H2(g) +
