Description : Explain the relationship between heat capacity and relative heat ?

Last Answer : The heat required to raise the temperature of an object by 1 K is called the heat capacity of that object. Again, if the relative heat of the material of the object is S , then the temperature of a ... the heat capacity of an object of mass m kg . Therefore , heat capacity = mass x relative heat.

Description : The snow on the mountains does NOT melt all at once when it is heated by the sum because: (1) It becomes very hard (2) It reflects most of the heat from the sum (3) it has a low specific heat capacity (4) it has a high latent heat of fusion

Last Answer : (2) It reflects most of the heat from the sum Explanation: Newly formed snow reflects about 90 per cent of the sunlight that falls upon it. This means that the sun is powerless to melt clean snow. And when ... on a spring day because of the sun's heat. It melts because of the warm air from the sea.

Description : On a cold day when the room temperature is 15°C, the metallic cap of a pen becomes much colder than its plastic body, though both are at the same temperature of 15°C, because - (1) metals ... metals (3) metals are good conductors of heat (4) plastics have a higher thermal conductivity than metals

Last Answer : (3) metals are good conductors of heat Explanation: On a chilly day, the room temperature is lower than our body temperature. Since metals have a higher coefficient of thermal conductivity than plastic, they ... from our fingers will flow to the metal cap much more quickly than to the plastic body.

Description : Steam at 100°C causes more severe burns than water at 100° C because – (1) steam has no specific heat capacity (2) steam has latent heat of vaporization (3) water has no specific heat capacity (4) water has latent heat of fusion

Last Answer : (2) steam has latent heat of vaporization Explanation: It is because steam releases its latent heat as it condenses, which is substantial. The heat of vaporization of steam is over 2000 J per gram. And when it releases that it's then 100 degree water, the same as boiling water.

Description : Heat given to a body which raises its temperature by 1°C is known as - (1) water equivalent (2) thermal capacity (3) specific heat (4) temperature gradient

Last Answer : (2) thermal capacity Explanation: Heat capacity or thermal capacity is a measurable physical quantity equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change.

Description : Which of the following has the maximum specific heat capacity? (1) water (2) piece of iron (3) piece of gold (4) chloroform

Last Answer : (1) water Explanation: The quantity of heat required to raise the temperature of a substance by one degree Celsius is called its specific heat capacity.

Description : Which of the following has got more heat capacity? (1) Iron piece (2) Water (3) Gold piece (4) Benzene

Last Answer : (2) Water Explanation: Heat capacity (usually denoted by a capital C, often with subscripts), or thermal capacity, is the measurable physical quantity that characterizes the amount of heat required to change a substance's ... (SI), heat capacity is expressed in units of joule(s) (J) per Kelvin (K).

Description : Water is used in car radiator because of its – (1) low density (2) easy availability (3) high specific heat capacity (4) low boiling point

Last Answer : (3) high specific heat capacity Explanation: Water is used in car radiators because the Specific heat capacity of water is high as a result of which it takes away the heat from engine better compared to ... coolant used in the radiator. If the radiator was to overheat the car would come to a stop.
