Water boils at `212oF` or `100oC` and melts at `32oF` or `0oC` . If the temperature of a particular day is `35oC` , it is equivalent to `85oF` (b) `90oF` (c) `95oF` (d) `99oF`

Water frezes at 0^(@)C and boils at 100^(@)C . Write an inequality to show the range of temperature (t) for which water is a liquid.

The average temperature for the first four days of a week is 40. 2oC and that of the last four days is 41. 3oC . If the average temperature for the whole week is 40. 6oC , then the temperature on the fourth day is 40. 8oC (b) 41. 3oC (c) 41. 8oC (d) 38. 5oC

The mean temperature of Monday to Wednesday was 37oC and of Tuesday to Thursday was 34oC . If the temperature on Thursday was 4/5 that of Monday, the temperature on Thursday was 34oC (b) 35. 5oC (c) 36oC (d) 36. 5oC

If the average temperature of first four days of the week was 39oC and the average temperature of the week was 40oC , then what was the average temperature of the last three days of the week? 39. 9oC (b) 40. 9oC (c) 41. 3oC (d) 42. 1oC

The mean high temperature of the first four days of a week is 25^oC whereas the mean of the last four days is 25. 5^0 C . If the mean of the whole week is 25. 2^oC , then the temperature of the 4th day is (a) 25. 2^oC (b) 25. 5^oC (c) 25. 6^oC (d) 25^oC

Assertion : The normal boiling point of water is 100 C^(@) and standard boiling point of water is 99.6 C^(@) . Reason : The temperature at which vapour pressure of liquid is equal to the external pressure is called boiling temperature at that pressure .

In a triangle, an exterior angle at a vertex is 95^0 and its one of the interior opposite angle is 55^0 , then the measure of the other interior angle is (a) 55^0 (b) 85^0 (c) 40^0 (d) 90^0

In Figure, A O B is a straight line. If /_A O C+/_B O D=85^0, then /_C O D= (a)85^0 (b) 90^0 (c) 95^0 (d) 100^0
