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 compare this value with the accepted (published) value for alum (92.5°C). The second test detennines the water of hydration present in the alum crystals. The third test is a chemical test to detennine the percent sulfate in your sample of alum. OBJECTIVES In this experiment‚ you will • • • • Detennine the melting temperature of a sample of alum. Detennine the water of hydration of a sample of alum. Detennine the percent sulfate of a sample of alum. Verify the chemical fonnula of a sample of

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. For example‚ if a sample of copper sulfate pentahydrate is heated‚ the bright blue crystals of the hydrate are converted to the white‚ powdery‚ anhydrous salt.
