Question

Which of the following statements is/are CORRECT? A system is defined as an object or collection of objects being studied. Surroundings are defined as the entire universe, including the system. in an endothermic reaction, heat is transferred from the system to the surroundings. 1 only 2 only 3 only 1 and 3 1, 2. and 3 Which one of the following statements is INCORRECT? Energy is neither created nor destroyed in chemical reactions. Kinetic energy is the energy that results from an object's position. Exothermic processes transfer heat from the system into the surroundings. Increasing the thermal energy of a gas increases the motion of its atoms. Energy is the capacity to do work. Specific heat capacity is the quantity of heat needed to change the temperature of 1.00 g of a substance by 1 K. the quantity of heat needed to change the temperature of 1.00 g of a substance by 4.184 K. the capacity of a substance to gain or lose a 1.00 J of energy in the form of heat. the temperature change undergone when 1.00 g of a substance absorbs 4.184 J. the maximum amount of energy in the form of heat that 1.00 g of a substance may absorb without decomposing.

Explanation / Answer

24) a

System is an object under thermodynamic study

Surroundings is the universe excluding system

In endothermic process heat is gained from surroundings

25) b

Kinetic energy is not due to object's position ,it's due to motion of atoms of object, remaining all options are correct

26) a

Heat capacity of a substance is heat required to raise the temparature of 1 gram of a substance by 1k
