When there's a temperature difference between two objects, heat is transferred from the hotter object to the cooler one. What is the name for the state reached when they are both at the same temperature?

The graph shows the relationship between the mass of an object and its specific heat capacity. Assuming the temperatu re change is 20^circ C calculate the change in internal energy when the mass of the object is 20kg. Give your answer in kJ and to 2 decimal places if needed. square square square square square square square square square square square

Which of these statements regarding INCREASING energy efficiency is TRUE? You can REDUCE heat loss in a system by using a thermally CONDUCTIVE material You can REDUCE electrical energy loss in a lamp by using THIN FILAMENT bulbs [BOTH of these] [NEITHER of these]

Electrical CONDUCTORS have (1) resistance, this means that a (2) current will flow through them. 1: low; 2: high 1: high; 2: high 1: low; 2: low 1: high; 2: low

A (1) breaks the circuit if a fault in an appliance causes too much (2) to flow. 1: fuse; 2: current 1: fuse; 2: voltage 1: LDRs; 2: voltage 1: LDRS; 2: current
