1- Change in temperature is a physical input variable of a sensor. Select one: True False
TRUE OR FALSE 1.) In rheology, food materials of higher viscosity have higher resistance to flow. 2.) Specific heat is the amount of heat needed to raise the temperature of a unit mass of an object one degree higher without change of phase 3.) Surface area, is related to size but also depends on particle shape. 4.) Size can be correlated with weight given that the material has more or less uniform composition. 5.) Latent heat of fusion is the amount of heat that must be removed to convert water to ice and is also the same as the amount of heat added to convert ice to water.
