Essay on Heat Stroke

On day 10, the 75o Control plants grew an average of 4.55 cm. This shows that room temperature is good for plant growth. The 100 Watt (110o) plants all died by day 7 showing that extreme heat stress is very bad for plant growth. Some of the plants died on day 5 and one never sprouted at all, but all were dead by day 7. The 50 Watt plants all died on day 6, which means that 85o is worse for plants than 1100 because they survived for a shorter…

Where M.R is the moisture loss ratio, M_0 is the initial moisture content, M_t is the moisture content at time t, M_e is the equilibrium moisture content, t is time (minutes), and a, b, c, and k are constants. For the effectiveness of diffusivity, Fick’s equation was used (5) to estimate the dehydration kinetic of different osmotic conditions. M.R=((M_t-M_e)/(M_0-M_e ))=〖8/π^2 e〗^((-(π^2 Dt)/(4L^2 )) ) …(5) Where D is the effective diffusivity, and L is the length of the (cubical) sample.…

In Greek, this is an onomatopoetic word. This means it’s a word that imitates the sounds associated with the objects or actions it refers to (like the word buzz in English sounds like the sound a bee makes when he is flying around). The word zeloo imitates the sound of boiling water, and it literally means to bubble over because it’s so hot! In a positive sense, zeloo is to be zealous in the pursuit of good, to desire earnestly, to strive after, to pursue, to be eager to possess. In the…

Fig.7, shows that, the insulator behavior of the PVA for pure PVA. But, with increasing the time of reaction there is an improvement in the electrical conductivity of the PVA-Ag nanocomposite films. Fig.7 shows that, the (I–V) characteristic of the samples, and the inset of Fig. 7 shows the relation between the conductivity and time of reaction. Then, the dc conductivity was calculated at the (voltage = 10 V) using the relation. (S/cm) Where (d) is the sample thickness, (A) is the area of…

Two computation cases were introduced, one with a polyurethane graft and another with a silicon rubber graft. The computations were done under a pulsatile flow. Both cases were computed under maximum peak pressure as mentioned in the method section. The flow volume rate is expressed by integrating on surface as followed: Q=∬_A^ ▒v.dA (5) By integrating flow volume rate in time…

The sun was up to death. It was really hot. I felt as if the only to survive such a day was to sweat a lot. Of course, I was sweating. A lot. My stomach was aching. I have not eaten since that morning. I have spent almost two days just eating some bread with butter. Just a day before like this, I was notified by the U.S. Embassy Brazzaville that I failed my TOEFL test. The Fulbright Fellowship was no longer within my reach. The burden of the pain was still running all over my body. My dream was…

packs help them work. 2. Instant hot and cold packs work by using chemicals that wither absorb a lot of heat quickly or release heat when absorbed in water, when a process absorbs a lot of heat it’s called an endothermic reaction ; when a process releases a lot of heat it’s called an exothermic reaction, the chemical ammonium nitrate Is quite often used in cold packs because it absorbs a lot of heat when soaked in water, water and…

Analysis Experiment #1 (Solid) a). My hypothesis was incorrect because I thought the fire going around the brass ball would make it smaller and when the ball through the hoop it would fit easily. I was wrong because the heat made the particles expand which lead to making the brass ball bigger. My second hypothesis was correct; I had thought the water would make the ball smaller and therefore fit through the hoop easier. The water cooled down the ball making the particles contract. When we…

Design- In this experiment we selected the happy sack to use for our experiment, as this sort of ball doesn’t bounce when dropped to the ground and this then gives us more accurate data for us to compare with the theoretical time. To record the closest accurate time and distance we could get, the equipment we chose to use, were two stopwatches so that we could compare the human reaction times and a tape measure to correctly measure the distance that the ball is going to fall from; which counted…

This experiment’s aim was to find the alcohol with the highest energy output when burnt using specific heat capacity of calorimeters. This data gathered only partially supported the hypotheses stated. There is an apparent trend between the heat energy of the alcohols and the amount of carbon atoms in the alcohols in the graphs shown. The first experiment (first graph) shows the results of the tests with a controlled calorimeter height of 20 centimeters. This means that the calorimeter, rather…
