- Question
Which of the following is not an intensive property?
Options- A. Weight
- B. Density
- C. Refractive index
- D. Melting point
- Correct Answer
- Weight
ExplanationAn intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example, the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system, if the system is divided in half, the mass and the volume change in the identical ratio and the density remains unchanged. Additionally, the boiling point of a substance is another example of an intensive property. For example, the boiling point for water is 100 °C at a pressure of one atmosphere, a fact which remains true regardless of quantity.

Correct Answer: impair the racial qualities of future generations either physically or mentally
Explanation:
Eugenics is the study of altering human beings by changing their genetic components.
It is the study of the agencies under social control that may improve or impair the racial qualities of future generations either physically or mentally.
Correct Answer: On the Top
Explanation:
Macronutrients are located on the Top of a Nutritional Label.
Macronutrients are essential substances that the body needs to survive and develop. There are 3 main Macronutrients:
1. Fats
2. Proteins (and)
3. Carbohydrates.
The nutritional label is an important part of any food package. Since the Macronutrients refer to a list of nutrients that we need daily in a pretty large amount are the most important nutrients to sustain our living, commonly they are written on the top of the Nutrition Labels.
Correct Answer: Contagious
Explanation:
A Disease which spreads by contact are Contagious.
Infectious diseases : These are caused by microscopic germs such as bacteria or viruses that get into the body and cause problems. Some but not all infectious diseases spread directly from one person to another. Infectious diseases that spread from person to person are said to be contagious. Some infections spread to people from an animal or insect, but are not contagious from another human.
Contagious diseases such as the flu, colds, or strep throat spread from person to person in several ways. One way is through direct physical contact, like touching or kissing a person who has the infection. Another way is when an infectious microbe travels through the air after someone nearby sneezes or coughs.
Fatal Diseases : Diseases leading to failure or disaster.
Incurable Diseases : Diseases of a sick person not able to be cured.
Correct Answer: Poor Hygiene
Explanation:
The Biggest cause of Foodborne Illness is Poor Personal Hygiene.
Foodborne Illness is caused by consuming contaminated foods or beverages. Many different disease-causing microbes or pathogens can contaminate foods, so there are many different types of foodborne illnesses.
Correct Answer: Telemetry
Correct Answer: 3
Explanation:
Tablespoon > Teaspoon
In US & UK, 1 Tablespoon = 3 Teaspoons.
Correct Answer: moderate tempatures
Explanation:
The moderate temperatures allow Earth to maintain bodies of water into its normal state.
Changes in the bodies of water in terms of volume and structure would change due to the change in temperature.
Correct Answer: capillaries of the active muscles will be engorged with blood.
Explanation:
During vigorous exercise capillaries of the active muscles will be engorged with blood.
Correct Answer: Raw carrots
Explanation:
Cooked food create an enabling environment for bacteria to grow because of their moisture content and because of the normal temperature of the food. Raw food does not offer suitable conditions for bacteria growth.
Hence, raw carrots does not support bacterial growth.
Correct Answer: Talc
Explanation:
Cosmetic powders are prepared from Talc.
Face powder is a cosmetic powder applied to the face to set a foundation after application. It can also be reapplied throughout the day to minimize shininess caused by oily skin. There is translucent sheer powder, and there is pigmented powder.
