A block of dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5 degrees C). Dry ice also has the very nice feature of sublimation -- as it breaks down, it turns directly into carbon dioxide gas rather than a liquid.
Credit Accounts: Negative information remains for 7 years from the initial missed payment that led to the delinquency. Active positive information can remain indefinitely (if an account is closed that has been positive, then it will typically remain on your report for 10 years after the date the account is closed). Collection Accounts: A collection account remains for 7 years from the initial missed payment that led to the collection.
Keep in mind that closed accounts do not simply fall off your credit report, and you should periodically check your report to ensure that closed account information has fallen off your report after a certain amount of time: Closed accounts paid as agreed can remain on your report for up to 10 years.
