A100.0 g ice cube at -10 degrees celsius is placed in an aluminum cup whose initial temperature is 70 degrees celsius. the system come to an equilibrium at 20 degrees celsius. what is the mass of the cup?

135 grams

Explanation:

As we know that,  

where,

= mass of ice = 100 g

= mass of aluminium cup =? g

= final temperature  =

= temperature of ice =

= temperature of aluminium cup=

= specific heat of ice=

= specific heat of aluminium cup =

Now put all the given values in equation (1), we get

Therefore, the mass of the aluminium cup was 135 g.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
