10% Can money buy happiness? People have always wondered 1. money really makes them happy. Researchers used to believe that it is up to a certain point happiness increases with income: beyond an annual income of $75,000, people are no happier with higher salaries. 3., recent studies have indicated that happiness still increases when salaries are higher than $75,000. The main reason that money seems to bring happiness is 4. more money can bring greater financial security. Daily activities such as grocery shopping are easier when most of the anxiety regarding what 5. is removed. In this way, money could be viewed as a solution problems. 6. one's on individual Most studies related to this question are based on averages rather than experiences. 7., there are many exceptions to the rule that happiness increases with 8. making $25,000 per year. By contrast, one's income. Some people are satisfied others feel that millions of dollars are required 9. their desired lifestyles. Compared with averages, the individual items that people spend their money on may be truer measures of happiness. A few studies have indicated that people are happy 10. they spend their money on specific items. This suggests that although having all the money in the world may not make you happy, it would give you more choices in purchasing the items you want.

問個 為什麼氣泡會往上浮啊?氣泡的蒸氣壓造成的力不是四面皆同嗎 那它為什麼會往上浮?

三、沸騰 定義:1.當液體在容器中被加熱,通常在容器底部加熱處形成氣泡(bubbles),當溫度 到達某一程度,蒸氣氣泡形成,經由底部上升至液面破裂,此時,我們說此液 體正在沸騰(boiling) 。 2. 液體沸騰的溫度決定於作用其上的壓力,如下圖所示。對於一個氣泡而言,為了 溫度處於能形成和長大,其內之壓力P,至少須等於P,而後才能上升接近液面,不過, 弗腾. 簡直是液體的蒸氣壓,所以我們得結論:當液體的溫度處於其蒸氣壓等於作用於 其液面的外壓時,此液體就可沸騰。壓力1atm(即101.3kPa)時,液體沸騰的 溫度,稱為正常沸點(normal boiling point),例如,水的正常沸點是100℃,而 苯的正常沸點則稍低,80℃。水的正常沸點100℃ 表示水在100℃時之蒸氣壓 為760 torr;酒精的正常沸點 78.4℃表示乙醇在78.4°C時之蒸氣壓為 760 torr; 二乙醚的正常沸點34.6℃表示二乙醚在34.6℃時之蒸氣壓為760 torr。 S P2 每單位面積上的大氣壓力 液面 液面 ·液體的氣泡 蒸氣分子撞 頸蒸 三 擊氣泡界面 意識器容空氣泡- 而向外推壓 a 蔬果 Pi 高炎 (a) ④當P大於P時,液體沸騰,氣泡由底部上升至液面,氣泡的壓力至少要等於 外壓,才能存在。 大氣壓力經液體向氣泡推壓 (b)
