Answering Questions

Maggie's first 'cause it is easy.

Where does Beau stay when he is on placement?

The hospital puts him up. If he wasn't renting then he would have to pay $150 (I think) a week for this, but since he pays rent and costs at our place then it is free. When I was on section as a teacher I had to find my own accomadation and TCol would only give you $500 for the 5 weeks you were away, including the cost of you actually going away.

Preq's questions

What's up with water evaporating when it isn't boiling?

This is basically a matter of diffusion and concentration gradients. Some water particles near the surface of the water manage to get enough energy to break away from the liquid and then they just float away. That happens enough and all the water evaporates. Much more likely to occur in a saucer than in a cup because if the partlicles touch the side of the cup they can condense back down again. Remember that it is both pressure and temperature that determines any substances state (or phase).

What's the difference between steam and water vapour?

As far as I can tell, temperature. Steam is very hot water. Water vapour is at regular surrounding temperature, but still in gaseous state 'cause it's all spread out or something. eg, straight from a kettle = steam, humidity in air = water vapour.

Tada!

Hope this has been enlightening! Feel free to ask other questions and I'll try and answer them.

In other news, weekend was mellow and good.

Beau managed to get up before me on Sunday and made me breakfast in bed and tidied the kitchen while I had a bath!

Sass also vacuumed and did the dishes over the weekend.

Muggle and Pirip did the flat shopping!

I am feeling very spoilt and will be cooking butter chicken for the flat tonight. I will also be missing my love.

Point of Fashion: pants that I had thought were too tight, but now are not!
Current Obsession: Is my weight actually going down or was it a fluke?
