PLEASE HELP ME DUE IN A COUPLE DAYS YOU WILL GET 30 POINTS PLEASE HELP ME WITH ALL OF UM SCIENCE SORRY I CANT FIND IT IN PICK A SUBJECT

Brainstorm ideas about the shape, materials, and construction of the cup. Then draw your best design for the cup. Be sure to include exact dimensions, materials, and the placement of the cold pack compartment. Use text boxes to explain your ideas and show the measurements.

Remember to use the provided volume dimensions when designing your cup. For example, the total volume of the cup must be 750 cubic centimeters. The drink compartment must be 600 cubic centimeters to hold a 20-ounce drink. The cold pack compartment must be 150 cubic centimeters (the volume of the reactants in the chemical reaction from task 1). You may want to review how to calculate the volume of a cylinder or rectangular prism. please use cubic centimeters

Part E
What do you like best about your cup? What aspect of the design are you the most hesitant about?

In this task, you’ll refine Xavier's design of a cup that was meant to make drinks cold for campers.

Estimated time to complete: 1 hour

Use this information to answer the questions that follow:

Xavier used his knowledge of endothermic reactions and the measurements provided to build his own durable yet inexpensive cup for campers. The diagram shows Xavier’s design.

a short and wide cup that's 9.6 cm tall and 15 cm in diameter; a chemical reaction compartment that's 15 cm long and 4.4 cm in diameter inserts into the side of the cup
These are features of Xavier's design:

The lid screws onto the top of the cup and has an opening to sip the drink or insert a straw.

The lid and the handle are made from a recyclable metal.

The transparent cup is made of thick glass.

The chemical reaction compartment is a cylinder that opens to the side of the cup. It has a screw-on cap. There are holes in the cylinder for gas to escape during the reaction.

Campers who used the cup said that their drinks were definitely colder but that their beverages tasted different.
Part A
Compare Xavier's cup design with the criteria and constraints given. What parts of Xavier's cup design were successful? What parts were unsuccessful?


Part B
How could Xavier improve upon his design?

Part C
Question
Draw the refinements you would make to Xavier's design. Be sure to label and describe any changes you make. if you can please use picture.

Part A:

Xavier's cup design has some successful features, such as:

  • The use of a chemical reaction compartment to make drinks colder.
  • The lid with a sip opening or straw insertion.
  • The durable and recyclable materials used for the lid and handle.

However, some parts of the design were unsuccessful:

  • The transparent glass material of the cup is fragile and can easily break, making it not suitable for outdoor camping activities.
  • The chemical reaction might affect the taste of the drink, which campers have reported.
  • The cup's size and shape might not be practical for carrying around during outdoor activities.

Part B:

To improve upon Xavier's design, some suggestions are:

  • Replace the glass material of the cup with a sturdy and lightweight material, such as BPA-free plastic, which is less likely to break.
  • Use a chemical reaction that does not affect the taste of the drink, or place the reaction compartment away from the drink compartment to prevent the reaction gas from affecting the drink.
  • Consider a more portable and practical design for outdoor activities, such as a taller and narrower cup with a non-slip grip and a removable handle.

Part C:

Here are some refinements that can be made to Xavier's design:

  • Increase the height of the cup to 14 cm and reduce the diameter to 7.5 cm to make it more portable and easier to hold. Add a non-slip grip to the cup to prevent slipping while holding it. Replace the fixed handle with a removable and adjustable strap to make it easier to carry around.
  • A layer of insulation would be added between the drink compartment and the cold pack compartment to prevent the beverage from being affected by the cold pack.
  • The chemical reaction compartment would be made removable for easier cleaning and refilling.

Part E

I like that my cup design is made of durable and lightweight materials and has a non-slip base to prevent spills. However, I am hesitant about the placement of the cold pack compartment at the bottom of the cup, as it may make it difficult to drink the last bit of the beverage without tipping the cup.
