recorded; the change in temperature (∆T) was calculated by subtracting the initial temperature from the final temperature. The reaction was performed twice for every calorimeter. The heat capacity (Ccal) of each calorimeter was calculated using the formula‚ C_cal=(-〖∆H〗_rxn^o n_LR)/∆T [1] where ∆Horxn is the total heat absorbed or evolved for every mole of reaction and nLR is the number of moles of the limiting reactant. The ∆Horxn used was -55.8kJ per mole of water while the nLR was 0.005 mole

Exposure to extreme heat can have deadly consequences to anyone who does not take proper measures to protect themselves. “When the body does not regulate its own temperature and rises to critical levels this indicates the presence of a heat stroke which can lead to death. Symptoms of heat exhaustion includes headache‚ collapsing‚ fainting‚ nausea

and during diarrhea and fever when sick‚ the body must restore that used water or the body will become dehydrated. The effects of dehydration can range from minor to serious health issues‚ and that is why proper hydration is critical. Water is a very essential element in proper health maintenance and is the key to fighting dehydration. Why Water Is Vital As stated earlier‚ water is essential to health maintenance since over

Strength Assessment of Self Curing Concrete Curing is the process of controlling the rate and extent of moisture loss from concrete to ensure an uninterrupted hydration of Portland cement after concrete has been placed and finished in its final position. Curing of concrete must begin as soon as possible after placement & finishing and must continue for a reasonable period of time for the concrete to achieve its desired strength and durability as per relevant standards.

staying hydrated should be a top priority. While water is the preferred method for staying hydrated in the heat for many people‚ it is not the only option. If you or your kids do not like drinking straight water‚ or if you want to add some variety to your hydration routine‚ consider implementing some tasty alternatives. Watermelon Watermelon is over 90 percent water‚ making it a great hydration option. It can be cut into slices and eaten. It can be blended up and made into a smoothie. You can cut

Many hydrated salts can be transformed to the anhydrous (without water) compound by heat.
