Final answer:
The statement regarding blenders for custard sundaes is generally false as blenders are not typically used in sundae preparation. The question references various physics concepts such as phase change with salt and ice, solutes in pancake batter, the potential of solar sail spacecraft, and the specific heat of ice versus air.
Step-by-step explanation:
Understanding Phase Change and Latent Heat
Addressing the student's question about the use of a blender in preparing custard sundaes, that statement is generally b. FALSE. A blender is more commonly used for making smoothies or blending ingredients into a liquid form, whereas custard sundaes typically require the layering of custard (which is not blended) with toppings. For the actual questions provided for reference:
- True or False - When you sprinkle salt on an ice cube, the salt lowers the freezing point of water which causes some of the ice to melt. However, because the ambient temperature remains below the freezing point, the water quickly refreezes, which makes the ice and the thread stick together (True).
- The chocolate chips in pancake batter act as a solute, as they are the substance dissolved or mixed into the batter (b. solute).
- It is indeed possible to propel a space craft using solar sails by harnessing the momentum of particles emitted from the sun, known as the solar wind. This innovative propulsion method doesn't require fuel in the traditional sense (a. true).
- Regarding specific heat in the context of ice cream mixture and the surrounding air in a freezer, if we assume that the air has a smaller specific heat than ice, the statement is then b. Ice has a smaller specific heat, implying it absorbs less energy, which is incorrect in the context provided by the question.
Each question touches upon different aspects of physics, from changes in state and solution chemistry to properties of matter like specific heat and advanced concepts like space propulsion.
