I’m not about to do 24 homework problems for you.

Answer by hessc213
Agreed. Here’s a hint, though…try drawing pictures of what the question is asking

Give your answer to this question below!

So I buy these new pyramid tea bags. Guess what they are made out of plastic.I always thought heat and plastic was not good to put in your body. I called the co. and was told its PET plastic the same kind of plastic orange juice comes in . I don’t put my bottle of OJ in hot water so whats the deal here?

Answer by Israely Jew
Don’t buy it again. It’s a rip- off.

Answer by graciegirl
no no no that’s dumb don’t buy them anymore

Answer by Ellie S
I think it is the temp that matters. Water boils at 212 F. That is not as high as fats can get in a microwave. I think the big problem with plastics is when you reach temps where they start to melt. So….no microwaving in plastics. I would think an application such as a tea bag would be safe. But hey, if you’re worried, there is always loose tea, which I think tastes better anyway.

Answer by Jay
Not all plastics melt at 100 degrees C (which is what boiling water would be). There are many plastics that have a much higher melting temperature and are commonly used for cooking (e.g., there are plastic spoons that are used food cooking and can withstand several hundred degrees).

You can, believe it or not, put an OJ jug into boiling water without it melting. I wouldn’t suggest ingesting the water, since the inks on the outside of the jug might not be edible.

Answer by Patrick G
That is very wierd. I’d stay clear of that product. There are some plastics that are more safe than others when heated but its never a good idea to heat plastic that is associated with a product you consume.

Lantao just came back from the 103.5 KTU BeatStock hot dance concert held at the PNC Bank Arts Center in Holmdel of New Jersey! It’s awesome cuz the audio is so good! And you cannot believe that KTU put our CHARICE as the FIRST artist to perform in the lineup followed by others like Pitbull, Taio Cruz, Kelly Rowland, Kat DeLuna! WOOT, that really caught Lantao in a surprise with my equipment totally not ready yet!! Sorry, security is EXCEPTIONALLY TIGHT. No matter how hard Lantao tried to smuggle his professional videocam in, all effort just in vain cuz they search you like prisoners with open arms & legs including touching every part of your body for legal harassment LOL! Thank god that Lantao has another 007-type secretive videocam otherwise I would come back with empty hands! This time a contingency plan works out beautifully. ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄ ♥ Please Follow Charice in her official sites at: www.youtube.com www.charicemusic.com http www.facebook.com www.myspace.com ♥ Charice’s self-titled debut album is available now at: iTunes: wbr.fm Amazon: wbr.fm and www.charicemusic.com ♥ Please also Visit her fan sites at: charicemania.com iam.charice.tv forum.charicediva.com www.chasters.us diva.charicemusic.ca chariceworld.com ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄
