     He has vowed that he will not stop building his business until it is worth ￡100 million. But hard-working

Owens can stop for at least a moment's celebration after making his first ￡1 million at the age of 16. Owens,

who has used a computer since the age of seven, began teaching himself basic web design at the age of ten

when he was given his first Mac computer. He used his pocket money to fund his first business project,

website Mac Box Bundle at just 14 which has made ￡700,000 since its establishment in 2008. Mac Box

Bundle sells a combination of popular Mac applications which are worth up to $400 together for under just

$100 and donates 10 percent of the money to charities.

    He then established an advertising company Branchr a year later and worked on the business after school

and at weekends. Branchr made a surprising ￡500,000 in its first year. Branchr works as a platform for

website owners to sell advertising.

     Owens, from Northampton, currently employs eight staff-all adults-around the UK and America as sales

and technical assistants. The young man lives with his parents. His mother who is a company secretary said

he was inspired to go into business after observing the huge success achieved by Apple's chief executive

officers (首席执行官) Steve Jobs.

     Owens said,"I think everyone has business sense in them, and they just need to gain experience and be

determined to make it. There is no magical formula (法则) for business, It takes hard work, determination

and the drive to do something great. My aim is to become a leading name in the world of Internet and mobile

advertising and push myself right to the top of the game.

     The teenager insists his professional success has not affected his personal life, and says his interests

include photography and playing the guitar. "My friends and I don't really talk about my success. To them

I'm just a normal teenager and it doesn't change anything between us."

新航天服（如图）是神七的一大突破，其采用的新材料能够防火与抗辐射。新航天服不但适合太空行走，还非常舒服，具有防微流星、真空隔热屏蔽、气密、保压、通风、 调温等多种功能，让航天员在太空中如同在地面上一样。假如在地面上航天服内气压为1atm，气体体积为2L，到达太空后由于外部气压低，航天服急剧膨胀，内部气体体积变为4L，使航天服达到最大体积。若航天服内气体的温度不变，将航天服视为封闭系统。

(1)求此时航天服内的气体压强；

(2)由地面到太空的过程中航天服内气体“吸热”还是“放热”。
