Statement 1: The time required in minutes for a heating/cooling curve to traverse one log cycle is represented by its slope and denoted as fh and fc respectively.

Statement 2: The time when heating started is called the zero time.

Statement 1: The cold point of a food item getting heated up by convection has its cold point at the centre of the container on the vertical axis.

Statement 2: The cold point of a food item getting heated up by conduction has its cold point at the bottom of the container on the vertical axis.

Statement 1: In a thermocouple, two wires are of different materials and a voltage difference is created due to the conduction of each material at the juncture and this gives us the difference in temperature in both metals and hence the temperature of the liquid.

Statement 2: The zone of slowest heating in a container is called cold point of a container.
