IMO, using thermocouple will be a good way to measure the temperature of the glass.

My english is poor (I am not a native english speaker) but I like to try it. Our research is to develop materials and techniques for pollution prevention. On the other hand, toxic chemicals often release into environment in our experiments. Here, I wonder if there also are toxic chemicals release into environment in your lab? If not, how do you avoid it?

Our research group is to develop materials and techniques to reduce environmental pollution. However, it can be often seen toxic chemicals release in our lab. For example, some toxic reagents release into water and some harmful organic gases release into air. I am just confused. Could anyone introduce the situation of your lab?

I think amoda is right. The exhaling and inhaling action get its power from the difference of pressure between inside and outside of lung. The air inside has a higer proportion of CO2, and the air outside has a higher proportion of O2, which will result in mass transfer (CO2 move to outside and O2 move to inside). Then the body gets its necessary O2 and releases its useless CO2.

I experience the same thing. I took an IQ test and got a score of 135 several days ago. But my girl friend had a higher score in spite of the fact that I am better than her in many aspects.
