Water cycle is defined as the way that water moves between being water vapor to liquid water and then back to water vapor. An example of water cycle is when water evaporates from oceans and then returns to the land in the form of rain. There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).

We all know that most metals are good conductors of heat, electricity and are solid at room temperature. Mercury is the only metal that is in liquid state at room temperature. It is used in thermometers because it has a high coefficient of expansion which makes it easy to move in the thermometers as per the temperatures. Mercury has a boiling point which makes it suitable to measure higher temperatures. In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked. The mercury expands and contracts with the changes in the temperature. The mercury thermometers are used in laboratory experiments, households and industrial applications.

| Quantity Used to Compare | Heat | Temperature |
| Definition | The heat of an object is the total energy of all the molecular motion inside that object. | Temperature is the measure of the thermal energy or average heat of the molecules in a substance. |
| SI Unit | Joule | Kelvin |
| Unit | Joules, Calories | Fahrenheit, Celsius, Kelvin |
| Symbol | Q | T |
| Particles | It’s a measure of the number of atoms multiplied by the energy possessed by each atom. | It is like a level which determines the direction in which the heat will flow. It is related to how fast the molecule within a substance are moving. |
| Ability to do Work | It is has the ability to do work | It can be used to measure the degree of heat. |

The transfer of heat because of movement of the molecules of the medium; via mass transfer; is called convection or convection of heat.
Water and air are bad conductors of heat. But they do become hot, in spite of being bad conductors. Heat transfer in fluids takes place through convection.

An amino acids is an organic compound, and it serves as a building block for proteins. Each amino acid contains an amino group and a carboxylic acid group. When you consume food with amino acids, it turns them into proteins which are a source of energy. Amino acids are the building blocks for the proteins, enzymes, hormones and neurotransmitters that your body manufactures. All amino acids share a general structure composed of four groups of molecules: a central alpha-carbon with a hydrogen atom, an amine group, a carboxyl group, and a side chain.

- An object is said to be in motion when its position changes with time.
- If the speed of an object moving along a straight line keeps changing, its motion is said to be non-uniform.
- An object moving along a straight line with a constant speed is said to be in uniform motion.

- The partially digested food is absorbed by the duodenum of the small intestine along with the digestive juices from the liver, pancreas and its own walls.
- The liver secretes the bile juice which converts fat into tiny droplets so that their digestion becomes easy.
- The pancreas secretes pancreatic juice which breaks down fats into fatty acids and glycerol.
- The intestinal juice secreted by the walls of the small intestine breaks down starch and carbohydrates into simple sugars. These sugars are known as glucose. It also converts the proteins into amino acids.
- All these simple, broken down forms are called the digested food.

1km=1000m
1hr=3600 s
So 1km/hr= 1000m/3600s
=5/18
So jst multiply the number in km/hr with 5/18 u get the same thing in m/s

Thermometers can be classified as follows:
Clinical thermometer : Clinical thermometer is used to measures the human body temperature.
Digital thermometer:
- Digital thermometers are an advance to the existing clinical thermometers;
- Due to high toxicity of the Mercury present in clinical thermometers and difficulty in its disposal in cases when the thermometer breaks digital thermometers are manufactured that can measure the accurate temperature without the use of mercury.
- Digital thermometers do not use mercury and hence safe to use.
Laboratory thermometer: Laboratory thermometer is used to measure the temperature of things other than human body.

As green house protects the plants to inside it from the climatic conditions outside and gives it suitable temperature for growth that's why farmers do so. Farmers get many advantages, they have bountiful crops and their crops are also protected from birds and animals. One of the main advantages to growing in a greenhouse is that it offers you a longer growing season. Temperatures don't vary as much within a greenhouse, since the sun's radiation is trapped in the enclosure, retaining the heat within the structure. Growing seasons can be extended, even in cold climates.
