The aircraft was subjected to a test of temperatures of 65 degrees Celsius and plus 120 degress.

The temperature is always 78 degrees. That's the temperature in _________. A: Celsius B: Centigrade C: Fahrenheit

执行以下程序段，并回答下列问题。请注意，直接填数字，前后不要加空格等任何其他字符。 int fahr; double celsius; for (fahr = 91 ; fahr <= 100; fahr++) celsius = 5.0 * (fahr - 32) / 9.0; /* 语句① */ printf("%4d%6.1f\n", fahr, celsius); /* 语句② */ 语句①执行了 次 语句②执行了 次 循环体语句共执行了 次 当循环结束时，变量fahr的值是

What is the procedure of preparing the mixture?1)Put the carrageenan solution in a 55-60 degrees Celsius water bath.2)Incubate at 55 degrees Celsius in the dark.3)Dissolved a certain amount of gelatin and carrageenan with KCl solution in water bath.4)Add a certain amount of TG enzyme to the dissolved gelatin solution while cooling.5)Mix the gelatin solution and the carrageenan solution. A: 32154 B: 13524 C: 31452 D: 13254

在数值天气预报模型中进行计算或推导其他大气特性时,科学家首选的温标是() A: 开尔文温标(Kelvin) B: 华氏温标(Fahrenheit) C: 摄氏温标(Celsius    )

华氏和摄氏温度的转换公式为C=5/9×（F-32）。式中，C表示摄氏温度，F表示华氏温度。要求：华氏0℉～300℉，每隔20℉输出一个华氏温度对应的摄氏温度值。 代码如下,按要求在空白处填写适当的表达式或语句，使程序完整并符合题目要求。 #include intmain() { intupper=300,step=20; floatfahr=0,celsius; while(fahr<upper) { _________________; printf("%4.0f\t%6.1f\n",fahr,celsius); ________________; } return0; }

温度的刻画有两个不同体系：摄氏度（Celsius）和华氏度（Fabrenheit）。‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬请编写程序将用户输入华氏度转换为摄氏度，或将输入的摄氏度转换为华氏度。‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬转换算法如下：（C表示摄氏度、F表示华氏度）‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬ C = ( F - 32 ) / 1.8‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬ F = C * 1.8 + 32‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬ 要求如下：‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬ (1) 输入输出的摄氏度采用大写字母C开头，温度可以是整数或小数，如：C12.34指摄氏度12.34度；‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬ (2) 输入输出的华氏度采用大写字母F开头，温度可以是整数或小数，如：F87.65指摄氏度87.65度；‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬ (3) 不考虑异常输入的问题，输出保留小数点后两位；‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬ (4) 使用input()获得测试用例输入时，不要增加提示字符串

第三篇 Florida Hit by Cold Air Mass In January, 2003, the eastern two thirds of the United States was at the mercy of a bitterly cold air mass that has endangered Florida’s citrus trees, choked 3 northern harbors with ice and leftbewildered residents of North Carolina’s Outer Banks digging out of up to a foot of snow. The ice chill deepened as temperatures fell to the single digits in most of the South, with an unfamiliar dip below the freezing mark, as far South as parts of interior South Florida. Temperatures in Florida plunged, with West Palm Beach dropping to a record low of 2 degrees. "We couldn’t believe how cold it was," said Martin King, who arrived this week in Orlando from England "We brought shorts, T-shirt, and I had to go out and buy another coat." The temperature plunge posed a threat to Florida’s USS 9.1 billion-a-year citrus crop, more of which is still on the trees. Growers were hurrying to harvest as much of the fruit as possible before it was damaged by cold. "Time is of the essence in getting fruit to the plant," said Tom Rogers, a citrus grower who expected to see damage to oranges and grapefruit at that time. In Florida, Governor Jeb Bush signed an emergency order to eliminate the weight limit on trucks so citrus growers could get as much fruit to market as possible. Casey Pace, a spokeswoman for Florida Citrus Mutual, said growers had sprayed trees with sprinklers, which created a layer of ice and helped maintain a temperature near freezing. Citrus trees are considered in danger of damage if the temperature drops below minus 2 degrees Celsius for four hours or more. Snow ranging from a dusting to up to 30 centimeters blanketed the Carolinas, Tennessee and parts of Virginia. citrus n. 柠檬，柑橘；柑橘属果树 bewilder v. 使迷惑；使为难；……弄糊涂 sprinklern. 洒水器；洒水手 Celsius adj.摄氏的 shorts n. 宽松运动裤；男式短衬裤 Governor Jeb issue the emergency order because he ______. A: thought speed limit for trucks was unreasonable B: tried to improve the traffic condition of the express ways C: wanted to encourage trucks to transport as much fruit to market as possible D: wanted to stop mucks from carrying too much fruit to market
