The specific heat capacity of a pure substance can be found by dividing the heat needed to change the temperature of a sample of the substance by the mass of the sample and by the change in temperature. The heat capacity of a certain substance has been measured to be [tex]$3.08 \frac{J}{ g \cdot{ }^{\circ} C }$[/tex]. Suppose [tex]$350 . g$[/tex] of the substance are heated until the temperature of the sample has changed by [tex]$48.6^{\circ} C$[/tex]. Write an equation that will let you calculate the heat [tex]$Q$[/tex] that was needed for this temperature change. Your equation should contain only symbols. Be sure you define each symbol.
Answer (3)
In comparing fractions and decimals, 10/9 is closer to 1 and 2/15 is closer to 0, as determined by division and evaluating the resulting number. ;
To determine which number is closest to a given fraction, subtract each option from the** fraction** and find the absolute value of the result. The option with the smallest absolute difference is the closest. ;
9 10 is closest to 1, and 15 2 is closest to 0.
