Specific heat capacity of a substance X is 1900 {\Jkg}^{-1}{ }^{\circ} {\C}^{-1} means :

Correct Answer is : 1kg of substance X absorbs 1900J heat for 1∘C rise in temperature

Substance {\X} absorbs 1900 {\J} for 1^{\circ} {\C} rise in temperature

1 {\kg} of substance {\X} absorbs 1900 {\J} heat for 1^{\circ} {\C} rise in temperature

1 {\kg} of substance {\X} absorbs 1900 {\J} heat to increase the temperature

1 {\kg} substance {\X} absorbs 1900 {\J} heat to cool down by 1^{\circ} {\C}

Specific heat capacity of a substance

X

1900 {\Jkg}^{-1}{ }^{∘} {\C}^{-1}

means :

Substance ${\X}$ absorbs $1900 {\J}$ for $1^{∘} {\C}$ rise in temperature
$1 {\kg}$ of substance ${\X}$ absorbs $1900 {\J}$ heat for $1^{∘} {\C}$ rise in temperature
$1 {\kg}$ of substance ${\X}$ absorbs $1900 {\J}$ heat to increase the temperature
$1 {\kg}$ substance ${\X}$ absorbs $1900 {\J}$ heat to cool down by $1^{∘} {\C}$

Solution:

(b)

1 {\kg}

of substance

{\X}

absorbs

1900 {\J}

heat for

1^{∘} {\C}

rise in temperature.
