Matter - anything with mass and occupies space
accuracy - an indication of how close a measurement is to the correct result
precision - the degree to which a measurement can be replicated
meniscus - the curved top surface of a liquid column
volume - spaced occupied measured in cubic units
density - mass of an object per unit volume
The effect of an insoluble impurity, such as sand, on the observed melting point of a compound would be none. It will not depress or elevate the melting point of the compound. Instead, it would affect the reading if you are trying to determine the melting point of the compound. This is because you might be missing the actual melting point of the compound since you will be waiting for the whole sample to liquify. You would not be able to determine exactly that temperature because of the insoluble impurity would have a different melting point than that of the compound.

<span>Because that big old ocean has a HUGE effect on moderating temperatures. Kansas and Iowa don't have that advantage. Weather on either coast is always more even than weather inland - warmer in winter, cooler in summer. . -Answer from yahoo user.</span>
The stomach breaks down food with the help of acids called digestive juices. The correct answer to the given question is option "c". In reality huge amounts of hydrochloric acids are present as constituent of the digestive juices. This hydrochloric acid actually breaks down food. The hydrochloric acid also helps to kill the microorganisms that that comes along with the food. It helps in releasing an enzyme by the name of pepsin. This enzyme breaks down the protein molecules present in the food that has been eaten. The walls of the intestine are protected from the negative effects of the hydrochloric acid due to the presence of the protective coating of mucus. This powerful acid helps a person digest any food that has been eaten.
