Calculating Melting Time for 7.5g Ice Cube at 0°C

Click For Summary

Discussion Overview

The discussion revolves around calculating the melting time for a 7.5 g ice cube at 0°C, considering the heat transfer from the surroundings at a specified rate. The context includes theoretical calculations related to phase changes and heat transfer in physics.

Discussion Character

  • Homework-related, Mathematical reasoning

Main Points Raised

  • One participant presents a problem involving an ice cube's melting time, providing specific values for mass, temperature, and heat transfer rate.
  • Another participant encourages the original poster to share their attempts and challenges to facilitate assistance.
  • A different participant expresses urgency for help regarding a separate experiment related to electricity, mentioning a specific formula but not directly related to the ice melting problem.
  • A further reply suggests that writing in all capital letters does not enhance visibility and recommends starting a new thread for better responses.

Areas of Agreement / Disagreement

The discussion does not show consensus, as participants are addressing different aspects of the topic, with one focused on the melting time calculation and another on a separate experiment related to electricity.

Contextual Notes

There are no explicit assumptions or limitations discussed regarding the melting time calculation or the separate experiment mentioned.

An ice-cube has a mass of 7.50 g. The ice-cube is at 0 °C.
Heat from the surroundings reaches the ice-cube at an average rate of 1.25 J / s.
How long does it take for all of the ice to melt?
(specific latent heat of fusion of ice = 333 J / g)
A 35.5 s B 55.5 s C 2000 s D 3120 s

Hi NabeelIshaq! Welcome to PF! :wink:

Show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
 
I NEED HELP ASAP PLEASE!
DOES ANYONE KNOW THE METHOD OR WHAT THIS EXPERIMENT IS CALLED? ALL I KNOW IS IT IS TO DO WITH ELECTRICITY. ALSO YOU USE THE FORMULA OF ITV X 150
PLEASE HELP the image that I have of the experiment is in the link below THANK YOU

Writing in block capitals doesn't get more attention.

I recommend you start your own thread to gain a better response.
