When a metal object is dropped into cold water, it releases 4,715 J of energy to its surroundings, and its temperature decreases from 100.0 °C to 20.0 °C.  The mass of the object is 420 grams.  What is the specific heat of this material?   0.210 J/g°C 4.59 x 106 J/g°C 4.76 J/g°C 85.0 J/g°C

Which of the following represents the freezing of water? H2O(s) –> H2O(l) + energy energy + H2O(s) –> H2O(l) H2O(l) –> H2O(s) + energy energy + H2O(l) –> H2O(s)

Which correctly describes a phase change concerning water?    I. Cooling water vapor can cause a phase change to liquid water. II. When liquid water gains enough heat it will change to a solid. III. When water vapor gets hot enough it will turn into liquid water.  IV. Cooling liquid water will cause a phase change to water vapor.

# 1. Write a Python snippet that creates an email for a user. In a function called get_email,# prompt for the users first name, last name, birth year and PSU id.# Then call the function create_Email, which creates an email consisting of their first name, the intial of their# last name, the last two digits of their birth year, the first three digits of their PSU ID number, and ending# with “@psu.edu”# 2. Write a Python snippet that acts as a users car radio. Initially prompt them to pick from the menu of what# station to listen to : 1). Country, 2). Classic Rock, 3). Alternative, 4). Pop, 5). Acoustic 6). Sports# Once they choose a channel prompt them to: 1). Stay on the same channel (Repeats the question),# 2). Change the station (Calls the function radio_stations()), 3). Turn off the radio# Funtions used:# radio_stations(): This function prints the channel options for the driver to choose from# play_country: Changes the channel to country and displays that the radio is “now playing Jolene by Dolly Parton”# play_rock: Changes the channel to rock and displays that the radio is “now playing Kashmir by Led Zeppelin”# play_alternative: Changes the channel to alternative and displays that the radio is “now playing Buddy Holly# by Weezer”# play_pop: Changes the channel to pop and displays that the radio is “now playing Fireflies by Owl City”# play_Acoustic: Changes the channel to acoustic and displays that the radio is# “now playing Sitting, Waiting, Watching by Jack Johnson”# play_sports: Changes the channel to sports and displays that the radio is “now listening to local sports talk radio”# turn_off: Displays that the radio is off
