Will champagne that is stored for a long time in heat explode?

June 9th, 2010 by admin | 4 Comments | Filed in Asnwers

I am planning a long road trip across country, and I will be bringing some champagne. There will be long periods of time when the car will be left outside and will heat up to at least 120 F, it is the US summer after all. What I need to know is if champagne is stored for to long like this, will to much pressure build up and it could shatter the glass bottle it is in?

How long do you think it will need to be stored to explode if at all?
Thank you.
Can someone give me a bit more educated answer…

What is the minimum value of the temperature at which the engine takes in heat?

May 23rd, 2010 by admin | 1 Comment | Filed in Asnwers

The maximum possible efficiency of a heat engine which exhausts its heat at a temperature of 46.0°C is 76.0 percent. What is the minimum value of the temperature at which the engine takes in heat?

I have used the equation: e = 1 – (Tc/Th). This has not worked for me. I would like to know how this problem is done or at least told in which direction I should go to solve this problem.

What will happen if you cut a hole in a cookie sheet then heat it?

May 16th, 2010 by admin | 2 Comments | Filed in Asnwers

We know that metal expands when heated, so what will happen if you cut a hole the size of a quarter in the center of a cookie sheet, then pop it in the oven until it’s very hot? Will a quarter still fit in the hole? Will the hole be bigger or small and why?

Thanks!

When cutting a promo, what is the best way for a heel wrestler to gain heat?

May 16th, 2010 by admin | 4 Comments | Filed in Asnwers

Wrestlers use different tactics when gaining heat from fans. Many have mastered the art of being a heel, but some don’t always make the cut. There are two main opportunities for a wrestler to show off their “mean streak”. So when given the following two opportunities, what tactics must a wrestler pull off to be a successful heel?

1) During a match -What must he or she do?
2) While cutting a promo – What must he or she say?
