Explanation
Gases can be converted into liquids by cooling , a process known as condensation . As the temperature decreases, the particles of the gas slow down and come together, forming a liquid.

Explanation
Liquids can be converted into gases by heating , a process known as vaporization or evaporation. As the temperature increases , the particles of the liquid gain energy and move faster, eventually breaking free from the surface tension of the liquid and turning into a gas.

Explanation
Solids can be converted into liquids by heating, a process known as melting. This occurs when the particles of the solid gain enough energy to break free from their fixed positions and start moving freely, resulting in a liquid state.

Explanation
Matter can change from one form to another through various processes, including: Heating : Melting ( solid to liquid ), Vaporization ( liquid to gas ) Cooling : Freezing ( liquid to solid ), Condensation ( gas to liquid ) For example , ice (solid) can change to water (liquid) by heating, and water (liquid) can change to steam (gas) by further heating. Similarly, steam (gas) can change to water (liquid) by cooling, and water (liquid) can change to ice (solid) by further cooling.

Explanation
A pandemic is an epidemic of an infectious disease that has spread across a large region, for instance multiple continents , affecting a substantial number of individuals.

Explanation
Hypothermia is caused by exposure to cold temperatures for a long time . It can also occur after prolonged immersion in cold water.  Causes  Cold temperatures: Exposure to temperatures below 10°C for a long time Cold water: Prolonged immersion in water below 20°C Wet clothing: Wearing wet clothing in cold or windy weather Heavy exertion: Exerting yourself while in cold weather Dehydration: Not drinking enough fluids in cold weather Undereating: Not eating enough in cold weather

Explanation
The number used to represent one unit length of a bar or one picture on a pictograph. Scaled Picture or Pictograph Graph DEFINE. A pictograph that uses a picture to represent more than one unit. Scaled Bar Graph DEFINE. A bar graph that uses intervals of more than one uni

Explanation
Average of A & B is  ( A+B) /2 = 30  ⇒ A+B=60 ⇒ A= 60 – B —- (i)  ( B+C)/2 = 64 ⇒B+C = 64 ⇒ B= 64 – C—- ( ii )  Putting value of B in equation ( i )  ⇒ A= 60 – 64 +C ⇒ A = -4 + C —– ( iii)  ( C+A)/2 = 34  ⇒ C+A=68 ⇒ C = 68 – A —–(iv) Puuting value of A from eaquation ( iii) to eq. (iv) ⇒ C= 68 +4 -C ⇒ C =36

Explanation
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia; east of the Balkan Peninsula, south of the East European Plain in Eastern Europe, west of the Caucasus, and north of Anatolia in Western Asia.

Explanation
An apostrophe before a cell value forces Excel to interpret the value as text. This is mostly useful for values that look like a number or date.

Explanation
 Speed=14 sec/m​eter  To convert  m/sec————> km/hr multiply by 18/5  Speed = 14 x (18/5) = 50.4 km/h

Explanation
