Question
How many joules are equivalent to 350 cal of heat? (1 cal = 4.186 J )
Explanation
Given:
How many joules are equivalent to 350 cal of heat? (1 cal = 4.186 J )
These values define the system as per NCERT data.
Formula:
Heat in J = Heat in cal × 4.186.
This is standard NCERT relation.
Substitution & Calculation:
350 × 4.186 = 1465.1 J approx 1465 J .
Result:
The computed value matches expected outcome and confirms correct choice as per NCERT.
