Question

Thermal capacity of 100g of aluminum (S=0.2 call/gK) is
Given, one calorie=4.2 joules)

Answer 1

$\huge\underline{\underline{\bf \orange{Question-}}}$

Thermal capacity of 100g of aluminum (S=0.2 cal/gK) is given, one calorie= 4.2 joules

$\huge\underline{\underline{\bf \orange{Solution-}}}$

$\large\underline{\underline{\sf Given:}}$

• Mass (m) = 100g of Aluminum
• Specific heat ( c ) = 0.2 cal / gK

$\large\underline{\underline{\sf To\:Find:}}$

• Thermal Capacity ( Q )

$\large\underline{\rm Thermal \: Capacity-}$

Heat required to increase temperature by 1°C

✪$\large{\boxed{\bf \blue{Q = mc\triangle T} }}$

$\implies{\sf Q = 100 × 0.2 × 1}$

$\implies{\sf Q = 20 cal/°C}$

1 cal = 4.2 J (Given)

So ,

$\implies{\sf Q = 20 × 4.2}$

$\implies{\bf \red{Q = 84 \: J}}$

$\huge\underline{\underline{\bf \orange{Answer-}}}$

Thermal Capacity of 100g Aluminium is ${\bf \red{84J}}$.
