So for my lab report I need to write a hypothesis on calorimetry and specific heat. For this lab we explore how the specific heat of a substance can be determined using a coffee cup calorimeter.

An engineer decides to use a slightly weaker material rather than a stronger material, since she knows that the stronger material can break suddenly. this is an example of what? a choosing a material that will show warning before it fails b using composite materials that combine strength c using a material for multiple applications d using design techniques that increase efficiency and reduce cost
