If I created a box about 0.5m per side and I made it out of ice...
Homework Answers
If the sides are just made of solid ice then it will behave just like a box made of anything else or made of stone or anything. Slowly over time it will cool down to the same temperature as the air around it. However if you had a box of ice filled with water then instead of the water cooling down when heat is taken out of it from the cold environment outside it will create ice. Slowly the water inside it will freeze and as long as there

cork thermometer plastic lid ← stirrer insulator ring reservoir ice and water aluminum container Figure 5.1: A Simple Calorimeter In the other direction, when the phase change is from liquid to solid, the sample must release the same amount of energy. For water at its normal freezing or melting temperature, Lf=79.5 cal/g = 333 kJ/kg (5.2) This lab employs a double-wall calorimeter as shown in Figure 5.1 to measure the heat of fusion for ice. The calorimeter consists of an...

Why do we measure the volume of the flask in this experiment with water rather than using the volume listed on the side? Select all correct answers that apply. Must include all correct answers for full credit. The volume is not accurate on a flask to the number of significant figures required for this experiment The volumetric markings on the flask do not extend to it's full height...
Two infinitely long wires are arranged side by side. The current I, is pointing out of the page.
Problem 6. Two infinitely long wires are arranged side by side. The current I, is pointing out of the page. The current I1 is pointing into the page. The distance between the wires is d. Let the magnitude of the currents be equal. I = I) Find the direction of the total magnetic field at the following coordinates. Give the answer as a positive or negative unit vector i, j, or k.23. At (2d, 0) (A) rightward (B) up (C) out (D)...

I can't figure this one out at all. Any help would be appreciated. Here's the question: You will need to complete the functions to Toggle the Fries and Drinks sections by adding or removing the 'hide' CSS class I created. I have already created the function to Toggle Burgers and you can use that as an example to build out the full functionality. I have also made created the function to reset the form. Finally, to calculate the total, you...
