The measurement of heat means_________

The error in the measurement of the sides of a rectangle is 1%. The error in the measurement of its area is

The heat dissipated in a resistance can be determined form the relation : H = (I^(2)Rt)/(4.2) cal . If the maximum errors in the measurement of current , resistance , and time are 2%, 1%, and 1%, what would be the maximum error in the dissipated heat ?

Complete the analogy Ammeter: measures current :: __________measures potenial differce

Dipole moment is measured in the unit of _______

For measurement of heat,.....is used.

In a workshop a worker measures the length of a steel plate with a Vernier callipers having a least count 0.01 cm. Four such measurements of the length yielded the following values 3.11 cm, 3.13 cm, 3.14 cm , 3.14 cm. Find the mean length, the mean absolute error and percentage error in the measured value of the length.

The heat of formation of methane gas at 298 K is -74.894 kj when the measurements are made at constant pressure. What will be the heat of formation of CH_4 at the same temperature but at constant volume? (R =8.314JK^(-1) mol^(-1))
