Question
A calorimeter is typically made from a thin sheet of which
metal, known for its high thermal conductivity?Solution
Calorimeters are designed to measure heat changes during physical or chemical processes. To do this effectively, the container must allow rapid heat exchange. Copper is commonly used because of its excellent thermal conductivity and low specific heat capacity, making it ideal for precise thermal measurements.
Train 'P' travels at a speed of 45 km/h and crosses train 'Q' in 15 seconds while moving in opposite directions. Determine the speed of train 'Q' if the...
25.902 × 78.095 + 999.996% of 200.08 + 20.005 % of 7999.997 = ? × 15.008 × 33.009
45.1298% of (14.032 - 75.98) + 27.87% of √40001 = 449.98% of 24.098 + ?Â
Solve the following expression and calculate the approximate value.
630.11 ÷ 20.98 × 5.14 – 125.9 = √?Â
350 ÷ 5 + 30 % of 180 + ? * 12 = 48 * √16
5.55% of 8120 – 66.66% of 540 = ? – 28% of 5500
9214.39 - 6843.57 + 8435.22 + ? = 17620.47
